A comprehensive study of Guimard’s work in the field of marblework has yet to be undertaken. It is nevertheless clear that this field held his interest just as much as other areas of decorative art. Guimard worked with marble craftsmen from very early on, at least since the construction of Victor Rose’s tomb in 1892, and we know that he designed funerary monuments until 1929 (the project for the commemorative monument to the Victory of the Marne). This article provides an overview of his creations in the more limited field of marble fireplaces. A second article will discuss the recent restoration of the engraved decoration on a fireplace in the Trémois building (1909–1910).
We are not aware of any marble fireplaces in any of Guimard’s early architectural works, but it is quite possible that some existed. The first designs specifically created by Guimard may date back to the interior work on Castel Béranger (1895–1898). Guimard’s use of fireplaces there was in no way innovative: it followed well-established conventions for apartments and private residences, where the combination of the fireplace and the mantelpiece above it persisted from the 18th to the 19th century[1]. But as we saw previously, the presence of heat vent grilles indicates that the apartments at Castel Béranger had a mixed heating system, with radiators in the basement and fireplaces in the main rooms. These elements of the fixed decor, though not very efficient, were long considered indispensable to a private interior and were therefore used occasionally or during the shoulder seasons. The list of contractors recorded in the Castel Béranger portfolio mentions “Hénault. – Marblework,” followed by this note: “Following the death of Mr. Hénault, the marble fireplaces were executed by Mr. Maybon[2].” This latter firm, whose workshops and showroom were located on Rue Saint-Sabin in the 11th arrondissement, specialized in “artistic and commercial fireplaces.”

Within Group XII, Class 66—dedicated to the permanent decoration of public buildings and residences—featured, among other exhibits, Guimard’s display, which included several interior fragments, including a bedroom and its marble fireplace. A particularly well-crafted label, now preserved at the Forney Library, confirms that the fireplace was on display at Guimard’s exhibition booth.

At Castel Béranger, the fireplaces with marble mantels from the A. Maybon company were found in the bedrooms and living rooms of the apartments. The other rooms were fitted with mantels made of glazed stoneware (produced by Alexandre Bigot) or cast iron (produced by the Durenne foundry in Sommevoire). The mantels in the bedrooms, which are fairly simple, feature classic inserts made of flat white earthenware tiles.

This design is also featured in the rooms of Castel Val, with a unique twist: the color of the marble varies from room to room. To the best of our knowledge, this 1904 building by Guimard is the last to feature this fireplace design from the Castel Béranger period.
Apart from this building, perhaps for an exhibition, Guimard experimented with creating a narrowing effect using three flat plates of glazed lava.

Significant fragments of this glazed lava vessel have been recovered and are now in a private collection.

The fireplaces in the living rooms, which are more elaborate, feature a cast-iron or glazed terracotta insert crafted by Gilardoni & Brault.

Presumably to save money, the decorative elements on these two marble mantelpiece designs from Castel Béranger are primarily engraved in grooves. Guimard reused them for several years in other buildings. At the same time, however, he also used wood for a mantelpiece (at Castel Val) and, most notably, from around 1900 to 1908, glazed lava, which allowed him to add color to these mantelpieces in a subtle way.
However, the appeal of carved and engraved marble remained strong, and around 1904, new designs emerged in line with the evolution of his style. Those at Castel d’Orgeval are very simple and feature flat earthenware panels for the insert.

Depending on the budget allocated and the room in which they are located, the mantelpieces in other homes vary in opulence.

These marble mantelpieces foreshadow the designs that appeared in the drawings featuring the standard sizes listed in the *Fontes artistiques de Guimard* catalog, published by the Saint-Dizier foundry in 1908. These standard sizes, designed to fit the most common mantelpiece models on the market, are presented across three plates, two of which bear the following note: “The marble can be obtained from: Société Anonyme des Usines et Carrières — Devillers et Cie — Marpent (Nord)[3].” On these plates, Guimard shows four different mantelpiece models adapted to three groups of inserts. The tallest and widest are the GA and GC, which are the same size (96 cm high and 110 cm wide). The GB model is of intermediate height and width (93 cm high by 100 cm wide).

As for the GI, GH, GG, and GE series, they are all the same height (90 cm), and their width increases by 5 cm with each model (from 75 to 90 cm).

For this final series, Guimard also designed a more monumental mantelpiece model featuring an ornate cast-iron panel at the top. The *Fontes Artistiques* catalog presents it in the widest GE model (above), but we also know of a narrower version with the GI insert (below).

But it soon becomes clear that the fireplace mantel designs shown in the plates of the artistic cast iron catalog are merely illustrative, as Guimard created a wide variety of different models. For example, within the GI, GH, GG, and GE series of narrower designs, we know of another mantel model that was actually produced (though its location is unknown) and is, in contrast, extremely simple.

For a GC insert, Guimard also designed a model for a mantel featuring bronze brackets at the corners.

This fireplace, numbered 1017, was installed in the living room of the Hôtel Guimard on Avenue Mozart. It is, in fact, the only fireplace in the hotel, as Guimard opted for central heating to save space in the modestly sized rooms of this very small property.

Among the photographs donated by Adeline Oppenheim to the Bibliothèque des Arts Décoratifs in 1948 is another mantel design with a refined silhouette that may have been photographed as a plaster model during the design phase.

These photographs, donated by Adeline Oppenheim-Guimard, are mounted on a sheet of heavy paper on which Guimard handwrote the model’s name and assigned it a number. This presentation suggests that he was planning to produce a catalog of fireplaces, just as he was considering others: chandeliers, hardware, mirror frames, vases, furniture, cutlery, and even tombs, for which the stonework would necessarily have to be commissioned from stonemasons. Most of these catalog projects never came to fruition, but they stand as an important testament, on the one hand, to Guimard’s desire to expand the scope of his creations almost infinitely, and on the other, to his wish to make them accessible to as many people as possible through mass production. On the eve of World War I, he was thus at the helm of a vast array of designs suitable for furnishing rental properties—whether modest or luxurious—as well as private mansions, all while maintaining tight control over the costs of their furnishings.
It is also worth noting that for his marble fireplaces, Guimard once again called upon contractors from northern France, as he did for the mosaics in the vestibules and halls of the Castel Béranger (De Smet in Lille), the earthenware versions of the Chalmont planters (De Bruyn in Lille), and the rugs and carpets (Honoré Frères and later Parlant & Biron in Tourcoing).
One cannot help but suspect the existence of a network of connections of which Louis Coilliot, the Lille-based ceramics dealer and client of Guimard, was likely a part.
Another telling sign that Guimard was closely connected to the marble industry is that in early 1908, just as the catalog of artistic castings published by the Fonderie de Saint-Dizier was about to be released, an unsigned article appeared, purportedly covering the 1907 Salon des Artistes Décorateurs but in fact devoted almost entirely to commenting on Guimard’s exhibition at that salon. No doubt due to a lack of access to the major decorative art journals of the time, which typically excluded the architect, it ended up in an obscure trade journal for the marble industry. This text offers a eulogy of the “Guimard Style” with an enthusiasm its creator had never enjoyed, not even when it was in vogue. The praise is so effusive that if Guimard was not the author himself, he must have firmly guided the writer’s pen and provided all the necessary arguments.
After the war, there is no evidence that Guimard created any new fireplace designs. In all areas of his work, he continued to reuse his older designs while occasionally—though rarely—creating new ones. The list of businesses at the Village Français town hall, built for the 1925 Exposition of Modern Decorative Arts, includes a fireplace manufacturer, the Société Industrielle des Pyrénées, but it is unlikely that Guimard designed a model specifically for this occasion. He continued, however, to use this heating method, as fireplaces are still present in a prestigious building such as the one at 18 Rue Henri Heine (1926), where the Guimards lived from 1930 to

Notes
[1] Its origins can even be traced back to Jules Hardouin-Mansart’s renovation of Louis XIV’s apartment at the Grand Trianon in the late 17th century. [2] Originally from Belgium, Albert Maybon’s marble company operated a quarry in Flaumont-Waudrechies, in the Nord department, in 1900. (source: Burgundy-Franche-Comté Regional Inventory). At the Paris World’s Fair, the company, representing Belgium, exhibited two marble columns from the Gochenée quarry near Namur (source: official exhibition catalog, Group XII, Class 66, fixed decoration of public buildings and dwellings). [3] The Société anonyme des usines et carrières Devillers et compagnie was a Belgian company founded in 1893 and operating in Marpent (Nord). This company is cited by Guimard in a letter published by La Construction Moderne in 1913 as one of the companies that made the greatest sacrifices to market the models designed by Guimard. It was dissolved in 1910 (National Archives of the World of Work). However, it likely continued under a new name, as the Société des carrières et marbreries de Marpent took it over in 1927 (Hauts-de-France Inventory, Presentation of the Municipality of Marpent).Translation: Alan Bryden

In the apartment of one of our members, located in the Trémois building designed by Guimard in 1909–1910 on Rue François Millet, the living room and dining room feature different Guimard marble fireplaces fitted with cast-iron inserts (GA and GB). We had noticed that the engraved decoration on the lintel of one of the mantels had been obscured. We therefore suggested the assistance of our friend Émilie Dominey, who, after leading guided tours for the Cercle Guimard for several years while pursuing training in sculpture conservation and restoration, is now working independently. We are reproducing the report of her work below.

Condition Report
Hector Guimard’s fireplace is framed by a mantelpiece decoration made of red, veined marble veneer. The top of the mantelpiece consists of a wooden panel covered with a painted faux-marble design.
This fireplace once featured a delicate, chiseled marble decoration on the upper lintel. It has been covered with a layer of plaster and retouched with paint—likely acrylic—in an attempt to recreate the marble’s veining.

Removal of Plaster
The plaster coating that covered the carved decorative details was removed using stonemason’s tools (chisel and mallet) and a scalpel.

Cleaning
After removing the old layers that had obscured the decoration, the entire surface of the marble mantelpiece was cleaned with water and a sponge.
Touch-up and Wax Application
Certain areas showing tool marks were lightly touched up with watercolor. The entire surface of the marble was coated with a thin layer of microcrystalline wax to restore the marble’s full luster.

It is worth noting that this same decorative motif can be found on other similar fireplace designs by Hector Guimard, notably at the Hôtel Mezzara, in a servant’s room on the second floor.

Built around the same time as Castel Béranger, from which it borrows certain features, Villa Berthe is considered Guimard’s first Art Nouveau work. Its striking rear façade—invisible from the street—clearly reveals the location of the staircase in the central bay and highlights the flights of stairs with rampant arches above each of the half-level windows.

It likely served as a partial inspiration for Henri Sauvage when designing the front facade of the Villa Majorelle in Nancy.

or recessed—as at Castel Béranger—which allowed for cost savings but may also be a sign of work carried out after the structural framework had already been completed.

The ironwork, which is also similar to that of Castel Béranger, consists of rolled iron bars that are bent and assembled using screws in overlapping layers or separated on the same plane by small cylindrical spacers through which screws pass.

It is always a pleasure to publish articles by Léna Lefranc-Cervo, who now holds a Ph.D. in the history of architecture and teaches at the École nationale supérieure d’architecture de Nancy. This article serves as a perfect follow-up to her piece “Protecting Parisian Art Nouveau Heritage: Initiatives and Networks in the Interwar Period,” as well as to her presentation “Hector Guimard and the Group of Modern Architects: Networks and Mobilization Strategies of a Modern Architect” during the Hector Guimard study day at Paris City Hall on December 3, 2024, and finally our article on Guimard’s use of different varieties of brick. This investigation into a setback suffered by our architect shows that a simple slanderous accusation—which could have been dismissed by a brief inquiry—required the persistent mobilization of his network of friends and professionals to secure the coveted decoration. This administrative inertia could also be indicative of the lingering effects of past hostility toward this innovator, as well as a certain inability to recognize him as one of the founding fathers of modern architecture and decorative arts in France.

The 1925 International Exhibition of Modern Decorative and Industrial Arts marked a triumph for modern architects. Having formed the Group of Modern Architects (GAM) in 1922, they had secured the major commissions for the International Exhibition. At the conclusion of the event, Frantz Jourdain, the Group’s president, described the exhibition as “a complete victory of modern art over all forces of incomprehension and routine[1].”

Portrait of Frantz Jourdain from 1923. National Library of France.
Shortly thereafter, Henri Sauvage, vice-president of the GAM, wrote to Paul Léon, director of the Beaux-Arts, stating: “You led us so well into the fray that here we are, all at once, and almost [unconsciously?], having achieved success[2].” Success was thus assured, and the Exhibition’s organizing committee then requested that the architects be promoted to the Legion of Honor, a process that would have finally established the Group’s members as the leading figures of the French architectural scene.
As early as 1926, several architects who had participated in the event were promoted to various ranks of the Legion of Honor. Henri Pacon, Michel Roux-Spitz, Pierre Chareau, Albert Laprade, Alfred Levard, Bernard Haubold, Edmond Malo, Robert Mallet-Stevens, Joseph Marrast, Paul Montagnac, Fernand Nathan, Auguste Perret, Henri Sauvage, and Pierre Selmersheim were made Knights. A few others were also promoted to the higher rank of officers, including Adolphe Dervaux, Ernest Herscher, and Charles Letrosne, as well as Pierre Paquet, Louis-Pierre Sézille, Louis Sorel, and Pierre Sardou. While the promotion of Dervaux, Sorel, Selmersheim, and Sauvage was seen at the time as a victory for the Group of Modern Architects, the group also suffered a bitter setback with the omission of Henri Favier, Gabriel Guillemonat, Pierre Patout, and, above all, its vice president and founder, Hector Guimard. Gathered to discuss the new promotions, the committee members expressed their outrage at “not finding in *L’Officiel* the names of certain members who rendered exceptional service[3].” The committee then sent a letter to the Minister of Commerce, and two protest letters were published in *Comœdia* on June 6, 1926. Yvanhoé Rambosson, the Group’s secretary-general, intended to publicly highlight the fundamental role of Guimard, who “played too dominant a role in the history of the modern movement to be forgotten[4]”:
“Let today’s innovators ask themselves if they would be doing what they do without having benefited from the experience of two generations. They will recognize Guimard’s splendidly revolutionary role and defend it alongside me. (…) It would be unjust to see many of those who entered the new forest through the breach he had made receive honors, without the first woodsman being rewarded[5].”

Portrait of Yvanhoé Rambosson, *Le Carnet de la semaine*, July 12, 1925, p. 12.
Following this appeal, Patout was finally awarded the rank of Chevalier. Guimard, however, continued to be sidelined in the recognition process. At the February 1927 committee meeting, the “Guimard affair” dominated much of the discussion among the members. New efforts were then made by the GAM to approach Bokanowski[6] and by Rambosson to approach Édouard Herriot. But the committee reported on the difficulties encountered:
“Our various expressions of indignation were met with total indifference. We have come up against high-ranking officials who have refused to inform themselves about such a delicate matter, or who have taken no action[7].” The committee, however, remained resolute: “We cannot leave matters as they are indefinitely. We have a duty to succeed in lifting the cruel injustice afflicting our comrade GUIMARD, and the Group will have to make his case its own personal concern[8].”
The Chancellery of the Order of the Legion of Honor had received a letter from an industrialist named Taté, owner of a factory and a plaster quarry in Thorigny-sur-Marne, who, without specifying the exact reasons[9], deemed Guimard unworthy of receiving this distinction[10]. The exact nature of this dispute is unknown. It is possible that it arose in the context of their collaboration on the construction of the town hall for the Village Français.

Letter from Taté to the Grand Chancellor of the Order of the Legion of Honor, dated May 18, 1925. National Archives, Léonore database, Guimard’s Legion of Honor file.
“Mr. Grand Chancellor,
I believe I am fulfilling my duty as a French citizen by warning you against the candidacy of:
Mr. Hector Guimard, architect, 122 Avenue Mozart, Paris
Architect of the Village Moderne Town Hall at the Exposition des Arts Décoratifs.
I will limit myself to pointing out that there is an information file on him at the Industrial Federation of Building Materials, 38 Rue Meslay in Paris.
The file and information are available to ALL MEMBERS of the employers’ unions affiliated with the Federation. Therefore, it would be in your best interest to review it for your own edification.
You may easily obtain a copy of this file through any member of our Board of Directors who is a Legionnaire.
Please accept, Mr. Grand Chancellor, the assurance of my highest regard.
N.B. — The members of our Federation’s Board of Directors are also the reviewers of the files and information that are communicated to the members of affiliated unions.”
In any case, Taté’s complaint triggered an investigation by the Ministry of Commerce, which brought all proceedings undertaken by the Exhibition Commission to a halt. The injustice was, it seems, sufficiently evident that the aggrieved vice-president of the GAM decided not to attend the banquet organized by the Group of Modern Architects in March 1927 in honor of the new members[11]. On this occasion, Guimard wrote a letter in which, while congratulating his colleagues on their success, he expressed his dismay at the injustice he was facing.
In Rambosson’s writings, these events came to be known as the “Dreyfus Affair of the Fine Arts.” The case was raised again at the GAM committee meeting on June 7, where Frantz Jourdain, lamenting the administrative delays, indicated that he would resume the efforts. But by November, nothing had yet been achieved. The GAM’s secretary-general then recalled the promises made by Paul Léon as well as those of Herriot and expressed surprise that the Group had not obtained satisfaction. It would, however, be another two years before the GAM architects’ efforts became more aggressive. On February 2, 1929, Rambosson sent the Minister of Commerce a letter countersigned by Jourdain[13] on behalf of the Group of Modern Architects.

For his part, Frantz Jourdain wrote to the Grand Chancellor himself the very next day, and a few days later, Jean-Baptiste Bienvenu-Martin, a senator from the radical left and former minister, also sent a letter exonerating the architect, using the same arguments as those put forward by Rambosson and Jourdain[14].

Emphasizing the irreproachable conduct of the GAM’s vice president, Rambosson, the Group’s secretary general points out that the promotion was requested by no fewer than three different organizations: the General Commission of the Decorative Arts Exhibition, the Group of Modern Architects, and the Society of Decorative Artists. He dismisses Taté’s complaint as a mere “dispute between architect and contractor, a common occurrence that falls solely within the jurisdiction of the Commercial Court or the Civil Court[15].” He notes that Taté has not brought the matter before either of these courts “and that it therefore does not appear that a letter sent under such circumstances can be taken into account[16].”
As for Jourdain, he points out to the Grand Chancellor that the charges against Guimard remain unknown: “The Ministers whom I had the honor of meeting on this subject, [illegible], have always assured me that no grievance remains against our candidate, and I find myself facing an inextricable situation for which you alone, General, can find a solution[17].” He continues: “If Mr. Guimard is innocent and worthy of the esteem in which all artists hold him, let us finally accept a 62-year-old artist who has demonstrated throughout his long career as much originality as talent, and who must finally be cleared of hypocritical, base, and cowardly attacks that could greatly tarnish his reputation[18].”
To support their cause, Rambosson had a short article published in Comœdia on February 22, emphasizing the role played by the vice president of the GAM in the emergence of modern architecture in France[19].
The interventions of the two men appear to have been decisive, and thanks to the energetic efforts of André Dezarrois, chief of staff to the undersecretary of state for the Fine Arts, André François-Poncet, the matter was finally resolved. Dezarrois inquired with the Industrial Federation of Building Materials, whose president replied that he had never been informed of any issue concerning Guimard and had never been asked to give an opinion on the architect[20].

This response brought the matter to a definitive close, and on February 28, 1929, Guimard was finally promoted to the rank of Chevalier. The news was immediately reported in *Comœdia*, and Frantz Jourdain, himself a Grand Officer, welcomed Guimard into the Legion of Honor. The resolution of the case thus demonstrated the solidarity and ability of modern architects close to Guimard to rally together.

This approach is characteristic of the positioning strategies of GAM members, who were convinced that the recognition of modern architects—and, through them, of modern architecture—could only be achieved through validation by official bodies. In 1895, Jourdain published *Les décorés, ceux qui ne le sont pas*[21] as a tribute to artists who had not received institutional recognition. Although the book surprisingly includes no architects’ names, it remains fundamental to understanding Jourdain’s approach, as he maintained throughout his life the ambition of securing official recognition for modern architects. For the president of the GAM, receiving an honor such as the Legion of Honor constituted an essential step in the fight for their recognition. Jourdain’s interest in this matter may seem surprising given his systematic—and often vehement—opposition to these very same official bodies. Jourdain is, in fact, primarily a progressive reformer who seeks to improve the situation of modern artists, yet he remains committed to the republican values of merit. It is not the institutions themselves that Jourdain questions, but rather the selection process they employ and, by extension, the judgment of those who constitute them. Jourdain believes that recognition for modern architects—and, through it, the triumph of modern architecture—will be achieved through democratic pressure exerted primarily through associations. His main objective is to secure official recognition for the modernists by replacing the established standards. For Jourdain, innovative architects must ultimately replace the Beaux-Arts architects—whom he considers mediocre—as France’s artistic glories. In his view, the innovators’ victory can only be achieved if there is a reversal of values within the democratic sphere itself.
Following this long-awaited victory, the GAM decided to hold a banquet in honor of the architect, which was organized in June 1929 at the Hôtel Lutetia.

This banquet is indeed presented as a festive occasion marking the recognition of Vice President Hector Guimard. The aim is to celebrate what the GAM will present as the architect’s official recognition and as a new victory for the Modernists, achieved thanks to the Group’s mobilization. Through Guimard, the entire founding network of the Group of Modern Architects is also being recognized. For the Group, the event apparently signified the State’s rallying to the cause of the Modernists. As such, the list of political representatives from the State and the City of Paris that the GAM planned to invite was impressive. No fewer than eleven representatives of national and Parisian administrations are invited, including André François-Poncet, Under-Secretary of State for Fine Arts, and his chief of staff André Dezarrois, as well as the Prefect of the Seine, the Police Prefect, the President of the Municipal Council and the General Council, the budget rapporteurs for Fine Arts in the Senate and the Chamber of Deputies, the President of the Civil Court of the Seine, and finally Paul Léon and Fernand David. Aside from the confirmed attendance of André François-Poncet at this banquet, the presence of other representatives from these administrations cannot be confirmed. The speech delivered by the Under-Secretary of State was, in fact, in line with the GAM’s views, and the senior official confirmed the recognition of the Group’s architects, noting that the Exposition had demonstrated that France had regained “its rightful place—as a creator, a guide, and a trendsetter[22].” This result “is the work of the bold pioneers, the leaders gathered here: Frantz Jourdain, Louis Bonnier, Henri Sauvage, Georges [sic] Sorel, Auguste Perret, Paul [sic] Bluysen, Louis Boileau, Adolphe Dervaux, and Lucien Woog[23].” The banquet, however, could not have played this role without the media coverage of the event provided by Rambosson in Comœdia. The Group’s former secretary-general presented the banquet as “a splendid celebration of modern architecture[24]” that brought together “the best of our innovators[25],” among whom he named: Auguste Perret, Sauvage, Bonnier, Dervaux, Boileau, Sézille, Sardou, Selmersheim, Patout, Tournon, Abraham, Favier, Gouverneur, Woog, and Bluysen[26].
Nevertheless, François-Poncet’s speech also constitutes a mixed tribute to Hector Guimard, despite the fact that he was the guest of honor at this dinner. Recalling his childhood memories in Cabourg, the senior civil servant then spoke of the interchangeable houses built at the turn of the century, followed by the arrival of modern architectural prototypes:
“And then, one day, Hector Guimard’s work appeared on this coast (…) For me, it was a source of perplexity and the starting point for some reflection. I did not consider the result to be entirely successful, and, to tell the truth, I did not have the overwhelming impression of any decisive beauty. But I was unsettled; for me, it was the revelation of an attempt, of a desire for innovation, whose underlying principle I felt deep down was sound and commendable; so I was particularly pleased to be able, some twenty-five years later, to pay tribute—and do justice—to the man who had given it to me[27].”

François-Poncet’s speech is indicative of the relative indifference and poor reception of Guimard’s work on the eve of the 1930s, as well as the difficulty in accepting the architect as a leading figure in modern architecture. In many ways, it foreshadows the obscurity and neglect into which the architect and his work would sink in the following decade. While Guimard could indeed count on the support of his friends and his network—who would always remain committed to defending his work, as Auguste Bluysen’s efforts in the 1940s would demonstrate—the relative lack of understanding surrounding Art Nouveau would overshadow the quality and significance of his work for at least thirty years.

Françoise Aubry, former curator of the Horta Museum in Brussels, had been a friend of the Cercle Guimard even before its founding in 2003. We met her on numerous occasions—in Paris, Brussels, and Barcelona—and corresponded with her frequently. Her expertise and experience guided us through the difficult journey toward establishing a Guimard Museum in Paris, and she graciously agreed to write the foreword for our first book dedicated to the Hôtel Mezzara in 2018, at a time when its future was highly uncertain.
Françoise was kind enough to respond to our request and send us a summary of the remarkable book she has just published on the Solvay hotel, one of Victor Horta’s masterpieces and undoubtedly his most luxurious work. On the occasion of the building’s repurposing—it has become a museum open two days a week following extensive restoration—she revisits the meticulous work of Yolande Oostens-Wittamer, published nearly thirty years ago.

In 1894, Armand, son of the great inventor and industrialist Ernest Solvay, married Fanny Hunter. The young couple chose to settle on Avenue Louise, at the time Brussels’ most prestigious boulevard, and to have a mansion built on a 950-square-meter lot. He chose Horta as the architect. His name was suggested by engineer Émile Tassel, for whom he was building a house nearby at 6 Rue Paul-Émile Janson, and by Tassel’s friend, Charles Lefébure, Ernest Solvay’s personal secretary. Horta was not yet very well known, but the novelty of the Tassel mansion caused a sensation. He would undoubtedly be able to build a residence equipped with all modern comforts (central heating, a bathroom, electricity) that would highlight the young couple’s boldness in the eyes of Brussels’ “high society”—a conventional crowd enamored with eclecticism. The Solvays’ fortune was recent and owed to the entrepreneurial skills of Alfred and Ernest Solvay. They were not heirs to a family tradition that might have constrained their choices and forced them into conformity.
Horta won the family’s trust and was commissioned for various projects, ranging from the family tomb at the Ixelles cemetery to the company’s laboratories on Rue des Champs-Elysées in Ixelles, including a château in Chambley, Lorraine, for Alice, who was married to Baron Henri de Wangen.
On September 3, 1894, Horta presented his initial plans to Armand Solvay. The project promised to be monumental. In his Memoirs, he speaks of a “giant’s work,” as the architect was also responsible for the interior decoration, including all the furniture, each piece of which was unique and custom-designed.
The building permit was granted by the City of Brussels on August 20, 1895. The construction project would be lengthy and could be considered complete in 1902 when the large canvas by the painter Théo Van Rysselberghe, *Reading in the Park*, was hung in the stairwell, blending beautifully into the colorful world created by Horta.

The Solvay hotel remained largely unchanged throughout much of the 20th century. During World War II, the glass roof covering the grand staircase was blown off when a bomb fell nearby. In the early 1950s, the Solvay family decided to sell the building, preferring to live in the green suburbs of Brussels. They offered to sell the mansion to the Belgian government at a reduced price. This generous offer was rejected, and it was not until late 1957 that the hotel was acquired by Mr. and Mrs. Wittamer-De Camps, who intended to establish their haute couture ateliers there. Various renovations were then carried out to adapt the mansion to its new purpose, and the skylight above the grand staircase was covered with a floor (today, the double-fan-shaped glass roof has been restored but is artificially lit, as the floor remains at the second-floor level). This alteration also deprived the winter garden of natural light (in the bedrooms on the first floor). The rooms on the second floor now form a single large space spanning the entire depth of the building.
Thanks are due to Mr. and Mrs. Wittamer, for it is likely that without them the Solvay hotel would have suffered the same fate as Horta’s other buildings on Avenue Louise: his second private home, at No. 136; the Aubecq hotel, at No. 520 (demolished in 1950); the Roger hotel, at No. 459 (completely renovated). After World War II, Avenue Louise was cut through by tunnels, and many of its mansions were replaced by apartment buildings.
The Solvay hotel was not designated a historic landmark until 1977, too late to prevent the construction of the two buildings that flank it today. After the death of Mr. and Mrs. Wittamer, their son Michel took over the management of the historic building. As for their daughter, Yolande Oostens-Wittamer, she devoted herself to research on Horta, culminating in a doctoral dissertation on the Solvay Mansion presented at the University of Louvain-la-Neuve (published in 1980). The current owner is Michel Wittamer’s son, Alexandre, who commissioned me in 2024 to write a book on the Hôtel Solvay, nearly thirty years after the one published by his aunt with Diane de Selliers in 1996. This book was published by Racine in 2025 and has been translated into Dutch and English, featuring photographs by Gilles van den Abeele and a series of plans by the firm Van der Wee Architects, which conducted a new survey of the mansion in preparation for its restoration.
The layout of the Solvay Mansion breaks with the tradition of Brussels mansions. The carriage entrance is still present and opens onto a driveway leading to the stables built at the rear of the lot. These were not commissioned from Horta by Armand Solvay but from architects who regularly worked for the Solvay firm (Constant Bosmans and Henry Vandeveld, 1898). The façade features two large bow windows, topped by balconies, which frame a curved central section. On the main floor, the living room balcony offered a view of the carriages heading to the Hippodrome or the Bois de la Cambre. The metal structures, painted in light ochre, are ubiquitous and radically new in the context of a luxurious mansion. Euville stone lends itself to subtle molding, while the more durable blue stone is used for the base, the frames of the balcony’s French doors, and a few horizontal bands.

The interior layout is unique: the floor plan is organized around two stairwells, topped by a glass roof, situated against the shared walls. The grand staircase, preceded by a vast hall opening onto the carriage entrance, leads to a landing from which it splits into two branches leading to the main floor. One must then cross a large landing providing access to the row of salons on the street side and the dining room on the garden side, before taking a more discreet staircase to reach the private floors.

Thanks to glass doors, the living rooms and dining room can open completely onto the stairwell, which is transformed into a grand entrance hall on days when guests are hosted. The entire space of the main floor can be taken in at a glance. These doors also allow natural light from the street- and garden-facing facades to flood into the heart of the house. Horta masterfully controls the flow of light and maximizes natural light because it lends a shifting vitality to the colors of the stained-glass windows and creates multiple electric light fixtures in gilded brass, whose stems are oriented to highlight the colors of the stained-glass windows once night falls, the intricate carving of the woodwork, the gold accents of the ironwork and decorative paintings, and the brilliance of the beveled glass. He also adheres to the tradition of placing enormous mirrors above the fireplaces to enlarge the space and multiply the brilliance of the lamps.

Horta was, of course, an confirmed architect, but he was also an accomplished artist when he combined colors in the manner of the painters of his time, applying Chevreul’s laws of complementary colors. In the wall decoration of the stairwell between the main floor and the first floor, orange gradually blends into green.
The first-floor landing separates the rooms reserved for the parents (the husband’s study, the wife’s boudoir, the bedroom) from those intended for family life (the study, the small, intimate dining room). The landing benefits from two sources of light thanks to the glass roof covering the second skylight and a second rounded glass roof that closes off an opening in the first skylight above the grand staircase. The landing is designed as a gathering place, an intimate space with its low sofas, metal floor lamps that evoke trees, and a garden represented by the floral stems frozen in the stained-glass window. This space invites timeless daydreams, as the real world seems so far away.

Between the first and second floors, Horta placed the bathroom on the mezzanine level. There, he boldly combines industrial materials such as white glazed brick with Carrara marble, set within American ash woodwork mounted on a red marble baseboard. Opposite the window, the door and cabinet panels are clad in beveled mirrors and frosted glass, used here for their texture and colors rather than to let in light, except in the door leading to the access corridor. The six panels form a splendid ornamental pattern. This bathroom exudes great refinement without being ostentatious. This is not the Hôtel de la Païva.
The walls of the final section of the stairwell are painted in an orange gradient fading to white as one approaches the glass roof. Bright orange arabesques outline a metal pergola, complemented by the glass roof and its foliage rendered in very soft yellow frosted glass. This arrangement highlights the fact that, in Horta’s work, the entire decorative system derives from the curve he imprinted on the metal. Rationally adapted to convey the material’s flexibility (in accordance with one of Viollet-le-Duc’s principles), the arabesque forms the basis of the wall decoration, which, in this case, represents architecture within the interior. The actual steel beams that frame the walls of the stairwell visually “support” painted arches, extended by the metal structure of the glass roof.
The service staircase, lit by a series of windows of various shapes on the garden side, provides access to a third floor, intended for the servants. The attic is spacious but cannot be fully utilized because its floor is pierced by the two skylights corresponding to the glass roofs set into the roof slope. This is a layout found in other buildings designed by Horta at the time: the stained-glass windows of the skylights crowning the stairwells must be protected from the elements by corresponding glazing in the roof.

Victor Horta, Solvay hotel, 224 Avenue Louise in Brussels, 1895–1902, private staircase covered by the glass roof of the north skylight. Photo by Gilles van den Abeele.
When examining the rear facade, the division of functions is rational. The most prominent part is the kitchen, which protrudes from the main structure (here, Horta departs from the principle of the basement kitchen); its roof forms a large balcony for the dining room, which is flanked by two stories. The narrow, solid structure of the service staircase is attached to it. Above the driveway, the utility room with toilet, the master bathroom, and the guest bathroom are stacked one above the other.
Another element of “modern” comfort, the ventilation was carefully designed by Horta, and a constant flow of air circulates through the hotel without the need to open the windows. The steam heating system originally fed radiators that have now been converted to gas by plumber and heating engineer Pascal Desmee, a delicate modification that required months of work. Recently (2021–2025), Alexandre Wittamer commissioned architect Barbara Van der Wee (who, among other Horta buildings, oversaw the restoration of the Horta Museum and the Van Eetvelde Hotel) to restore the façade and roof of the Solvay hotel. The metal structures had deteriorated and required complex repairs carried out by metalworker Luc Reuse. Many other skilled craftsmen (roofers J.M. Tong and his son, painter Chr. Feuillaux, carpenter D. Lutjeharms, master glassmaker Cl. Van Veerdegem-Vosch, etc.) participated in this exemplary project, which was awarded an Europa Nostra Prize in 2025.
We must be aware today of the fragility of these Art Nouveau buildings, to which access must be strictly limited. The staircase at the Horta Museum had to be reinforced because it was sagging under the weight of visitors, and it lacks the precious wool carpets that Horta had designed for the Solvay hotel. The maintenance and restoration of these exceptional architectural works depend on the availability of well-trained craftsmen. One might wonder whether public authorities will continue in the future to fund “heritage schools” and the conservation of historic buildings. Will future generations be drawn to these often arduous and demanding trades, rooted in a long tradition of craftsmanship where manual skill and intellectual ability go hand in hand?

The Solvay hotel, along with three other buildings designed by Horta (the Tassel hotel, the Van Eetvelde hotel, and Horta’s own home), were designated UNESCO World Heritage Sites in 2000—an international recognition of Horta’s work that unfortunately came too late to save the Maison du Peuple, which was demolished in 1965.

Since his projects were aimed at creating a comprehensive interior design, Guimard took an interest in floor coverings, whether rugs or carpets. As early as the Castel Béranger period (1895–1898), he commissioned several large rugs from a manufacturer whose name is not yet known with certainty. The only bibliographic reference to these rugs that we are aware of is the frontispiece plate in the Castel Béranger portfolio published at the end of [1] 1898 and its caption (in the table of plates): “TITLE—composition for rugs.”

In fact, their design incorporates only part of the frontispiece’s design: the lower left corner, mirrored in the other three corners, as well as the central motif of the lower border, mirrored in the upper border. It is, of course, possible that Guimard instead expanded upon and refined an initial carpet design to create the frontispiece’s design.
These wool carpets, which are very likely the first Art Nouveau-style models to have appeared in France, are extremely rare. They were obviously not intended for the tenants of Castel Béranger, who had neither the means nor the space in their rather modestly sized rooms, but rather for a clientele of wealthy collectors. Two of them have been sold on the art market over the past decade. One is larger in size: 4 m x 6 m.

The other one, which is smaller, measuring 3.45 m by 4.93 m, is a scaled-down version of the first.

This last piece recently arrived from the United States, where it was acquired by our partner, Hector Guimard Diffusion. It is in good condition, but restoration work is needed in several areas.

Both carpets are made of knotted wool with a short pile. Their orange-red background is framed by yellow, light orange, and pale blue borders.

The reverse side of these carpets clearly reveals the technique used. The “pixelated” effect, caused by the thickness of the stitches, does not lend itself well to Guimard’s curves, but it is mitigated by the large size of these carpets.

Neither of these two units bears a manufacturer’s mark, but they may have been produced by Honoré Frères in Tourcoing, the firm commissioned in 1897 to create the carpets for the three staircases of the Castel Béranger[2]. Their appearance is known from their reproduction in the Castel Béranger portfolio, where Guimard provided two color versions: one for the staircase facing the street (pl. 29) and the other for the staircase facing the courtyard (pl. 28). In these colorized reproductions, the surface texture is also consistent with that of knotted wool carpets. Given their narrow width and the delicacy of the patterns, their knots were necessarily small.

On a single sheet of paper preserved in the Guimard collection at the Musée d’Orsay, there are two drawings for these rugs, which are symmetrical to one another, bearing the note “Delivered to the manufacturer on March 29, 1897, P. Honoré frères” as well as a simplified signature by Guimard.

But these are not exactly the same designs as those reproduced in the Castel Béranger portfolio. If we isolate one of the two designs—for example, the one on the right—and examine one of the two borders, we see that to create the opposite border, Guimard rotated it by 180 degrees.

Whereas to obtain the design of the carpets as they were actually executed, he duplicated one of the two borders by reflecting it across a vertical axis.

For these stair carpets at Castel Béranger, Guimard took his attention to detail to the point of designing a unique model of studs to secure the rails, of which we have several units.

During the restoration work carried out in 2000, the stair carpets were roughly restored, and the wrong color was used for the staircase in the building’s street-facing lobby.

Just as he had done in other fields, with the aim of making his designs more widely available and lowering their cost, Guimard wanted to have his carpet designs produced. He therefore approached the firm Parlant & Biron, which had its Paris office at 13 Rue Poissonnière. We had long noted that this company was also originally from Tourcoing, but it was only very recently that we were able to establish with certainty that Parlant & Biron was indeed the successor to the Honoré Frère firm, thanks to the acquisition of a promissory note from the Gaston Honoré company, dated March 31, 1911, and bearing the overprint “PARLANT & BIRON, Sucrs.” The fact that this succession is indicated by a stamped overprint suggests that, in March 1911, it was recent enough that updated documents had not yet been printed. This document also reveals that Gaston Honoré himself succeeded “Maison V. Straub, Ch. Gérardin, Honoré Frères, réunies”[3].

Guimard thus secured the publication of his designs in a catalog. The copy held at the Bibliothèque des Arts Décoratifs contains only four unnumbered plates, all of which feature Guimard’s designs. Since this copy was donated by his widow, it is likely that the other plates were removed from the catalog in order to document simply the architect’s work.

Six designs for Parlant & Biron are available as rugs with a fixed width of 70 cm and sold by the linear meter in three grades, priced at 7, 8, and 9 F-or. The material used and the type of weave are not specified.

It is noticeable that the model shown on the right side of this plate appears to be that of the staircase at Castel Béranger, reproduced in shades of gray with greater clarity than in the two plates of the portfolio. In fact, however, this is the original drawing (GP 240), with its asymmetrical borders.

For the other model on this sheet, which is shown in two color variations, there are two watercolor studies by Guimard in the collection of documents donated by Adeline Oppenheim Guimard to the Bibliothèque des Arts décoratifs in 1948.

On a second plate of the Parlant & Biron catalog, a third design is shown in three colors. As with the two designs presented above, its clearly defined borders indicate that it is intended as a stair carpet or a hallway rug.

On the contrary, the three other patterns featured on the other two plates have no borders and are designed to be joined together (like wallpaper) so they can cover large areas and serve as a carpet. Once placed side by side, the strips are sewn together and then stretched out.

We think it is worth taking a closer look at the reference numbers for these six models and their variants:
3.366 – 9.341 for the Castel Béranger model.
13.663 – 9.359 and 13.663 – 9.361 for the bordered model shown on the same plate.
13.659 – 9.350; 13.659 – 9.351; 13.659 – 9.352 for a bordered model on a second sheet.
13.664 – 9.396 and 13.664 – 9.462 for a pattern with a seam on a third sheet.
13.653 – 9.391 for a pattern with a seam on this third sheet.
13.672 – 9.576; 13.672 – 9.578 and 13.672 – 9.807 for a pattern with a seam on a fourth panel.
The last four digits after the hyphen distinguish the color variations of identical patterns. We do not know the meaning of the number 9. As for the groups of numbers before the hyphen, they designate the models. Furthermore, we propose the following hypothesis: the number(s) before the period could indicate the year the model was added to the manufacturer’s catalog (Honoré Frères, then Gaston Honoré, then Parlant & Biron). Thus, the Castel Béranger model (3.366) would have been added in 1903, and all other models would have been added in 1913—that is, at the time Guimard was designing his mansion. This would give us a sixteen-year timeframe (from 1897 to 1913) of collaboration between Guimard and the manufacturer. Keep in mind that the date of 1913 does not necessarily correspond to the creation of these five models and that Guimard may have had access to them before they were published in a catalog.
Several photographs show Guimard using these rugs. One of them, undated, is likely a view taken inside Guimard’s workshops. It clearly shows the bordered rug 13.659 and, less clearly, beneath the desk and chair, the pattern-matched rug 13.653.

Pieces of the same pattern-matching rug (13.653) also appear in other photographs taken under similar conditions.

Finally, two of these seamless carpet designs appear in photographs taken inside the Guimard Hotel: once again, the 13.653, used as wall-to-wall carpeting in the bedroom.

Alongside this production for commercial purposes, Guimard continued to design large rugs. We have evidence of this in the form of a watercolor sketch with a particularly rich, even evocative, design. Although undated, it can be dated to 1903 or later and is housed at the Bibliothèque des Arts décoratifs.

We can see, then, that Guimard’s rugs and carpets reflected his stylistic evolution, with designs that, in some cases, could be seamlessly integrated into modern interiors.

Following two articles devoted to the door and window hardware of Castel Béranger, we continue our description of the other hardware pieces created by Guimard in collaboration with the Fontaine company or the Durenne foundry for his first apartment building. Some were produced for each apartment and can still occasionally be found in the building, though more often on the art market. Others were likely cast as one-of-a-kind pieces and have, for the time being, disappeared.
Found on every apartment landing door, the doorbell buttons feature a roughly square base plate whose central section appears crumpled and whose four corners seem flattened by the pressure exerted by the screws securing it to the wall. Guimard revisited this concept of material deformation on numerous occasions, such as in the transverse fasteners originally designed for the porticos of the metro’s open-air entrances.

Their mechanism (a spring-loaded push button) and, even more so, the term used in the captions for Plate 35 of the Castel Béranger portfolio-“electric bell buttons”-leave no doubt that electricity was present within Castel Béranger. Although the principle of the electric doorbell was patented as early as 1852[1], this source of energy—which was particularly modern in 1895–1898—does not appear to have been used for lighting there. In his portfolio, Guimard remains, moreover, very discreet about the lighting fixtures in use in the building. The lantern in the courtyard, with its chimney protected by a cap, could have been gas-powered. But it cannot be ruled out that, at the time of their delivery, the apartments were simply lit by oil lamps suspended from the ceilings, as we will see later.
This model of doorbell button was used by Guimard at least for the Castel Henriette[2]. But other locations may have existed, as evidenced by this example set into a stone (slate?) plaque whose contours follow those of the plate, smoothing them out. It is possible that this is the doorbell for the gate leading to the parish hall of the Salle Humbert de Romans. In that case, the electrical wire emerging from the right side and running along a stone joint indicates how Guimard intended the button to be positioned (rotated 180° relative to the photo in the portfolio).

Most of the original pieces at Castel Béranger met the same fate as other Guimard hardware: they were stolen and then collected or resold. As a result, most of the doorbells currently installed in the apartments are replicas.

Another type of electric doorbell appears on the same page of the Castel Béranger portfolio and is included under the same caption, “electric doorbell buttons.” This time, it is an electric bell, which was likely used to summon the servants. The apartments at Castel Béranger, which were intended for a clientele of the lower and middle classes, did not have a service area, but it was possible to rent maids’ rooms on the sixth floor. None of these bell pull handles are currently known to exist.

A third doorbell mechanism is the “bronze slider for the main entrance on an enameled lava plate,” reproduced on plate 35 of the portfolio. It was likely produced in very limited numbers and was probably installed only at Castel Béranger.

The metal elements can be seen in item no. 628, in a photograph donated by Adeline Oppenheim-Guimard to the Bibliothèque des Arts décoratifs in 1948. They appear alongside other hardware pieces from the same period or later.

This type of doorbell could operate mechanically (via a cable that rang a bell) or electrically [3]. Its position on the section of the gate between the gate leaf and the right-hand post suggests that it was likely an electrical mechanism, which takes up less space. The bell rang in the concierge’s lodge, where the concierge would then pull a cord to open the door.

Unfortunately, this slider was gone by 1963. A photograph taken that year shows that it had already been replaced by a standard electric doorbell button.

Another hardware item that was likely produced as a one-off is the faucet on the courtyard fountain.

Although the cast-iron fountain, which was likely originally bronze-plate, still exists, the faucet disappeared at some unknown point in time and was replaced by a plain faucet that is too short to fill a bucket placed in the central basin.

It is undoubtedly in the studs on the stair carpet rods that Guimard’s commitment to paying attention to every decorative detail is most evident (see our article on Guimard’s carpets and rugs). On what is necessarily a simple piece, Guimard incorporates a side pinch.

These studs were all removed at some unspecified time, but a significant number of them were recovered by Alain Blondel and Yves Plantin.

Currently, the stair carpets at Castel Béranger are held in place by rods secured with standard wall studs.
Originally, each apartment at Castel Béranger had a tiny bathroom equipped with a vanity unit designed by Guimard.

This economical piece of furniture, with its geometric lines, may have predated the Castel Béranger collection but was likely updated with metal hardware. The drawer knobs, towel rack brackets, and faucet base are made of “nickel-plated brass” and feature a design consistent with the other Castel Béranger styles.

To the best of our knowledge, two wash basins from Castel Béranger have survived. One of them was purchased by Hector Guimard Diffusion and will be on display at the Guimard Museum inside the Hôtel Mezzara.

During its restoration, it was necessary to reconstruct the faucet base using old photographs and to replicate the drawer knobs based on one of those from the other known example.

Guimard used these drawer knobs around the same time on several pieces of furniture, including his own desk, which was originally located in his architectural office on the ground floor of Castel Béranger and later moved to his new office on the ground floor of his townhouse at 122 Avenue Mozart.

Even something as insignificant as the handle on the fireplace screens in the apartments was the subject of a design. It is listed in the Castel Béranger portfolio under the name “copper shell for fireplace screens.” We are currently unaware of any surviving examples.

While there were fireplaces in the bedrooms, living rooms, and dining rooms of the apartments, the inclusion in the portfolio of a “bronze grid for the heat vents” indicates that Castel Béranger also had a supplementary heating system consisting of radiators in the basement and hot-air ducts.

We are currently unaware of any surviving examples, but two were later used by Guimard as ventilation grilles and set into the masonry: one on the right-side facade of the Hôtel Deron-Levent in Paris (c. 1907), the other on the street-facing facade of the Villa d’Eaubonne (c. 1907–1908).

We conclude this article with a few cast-iron hardware items, which were likely cast by Durenne in Sommevoire, unlike all those presented above, which are made of copper alloys and were probably supplied by the Fontaine company.
As we mentioned earlier, it is likely that the apartments at Castel Béranger did not have electric lighting. Nor is there any evidence that they had a gas lighting system. However, the fact that cast-iron hooks remain in some apartments, attached to an iron joist in the center of the rooms, leads us to believe that they were used to hang oil lamps that could be raised and lowered using a pulley to adjust the lighting and refill the fuel reservoir.

Only the model of the suspension hook intended for the living-rooms is mentioned in the portfolio. It was likely larger in size than those for other rooms. We are currently unaware of any surviving examples.

We currently know very little about other hardware items at Castel Béranger. These consist of decorative metal fasteners that punctuate the joists in certain rooms. They can be seen in two plates of the portfolio, on the ceilings of a bedroom (Pl. 40) and a living room (Pl. 49). These two rooms were part of the same street-facing apartment on the second floor that Guimard specifically used for the photographs reproduced in the portfolio. In the photo on plate 49, we can also see decorative fasteners on a metal lintel of the bay window, which Guimard took care to highlight with a touch of gold.

Though still present, these decorative cast-iron rings are less conspicuous and are not mentioned by Guimard in his portfolio; they adorn the joints between the balusters of the service staircase at Castel Béranger.

In an upcoming article, we will discuss Guimard’s hardware produced outside of Castel Béranger and shortly thereafter.

After an initial article devoted to the locks and porcelain knobs originally created for Castel Béranger, we continue our description of the other hardware created by Guimard with the Fontaine company, mainly to furnish the common areas and apartments of his first apartment building, but also several contemporary and later constructions up to the mid-1900s.
As we saw in the previous article, around 1900, Fontaine put together a prestigious portfolio featuring some of its most beautiful collaborative designs. The only plate relating to Guimard shows lock no. 276 (the only Guimard item to be published in Fontaine’s catalog) and the porcelain knob (which was actually produced by Sauzin) in the center. It also features other hardware from Castel Béranger: the bolt, the door handles in the common areas, the landing door handles in the apartments, and the handles and casings of the espagnolette locks, all photographed in much higher quality than in the Castel Béranger portfolio, where the appeal of the stencil coloring detracted from the sharpness of the photos.

The brass (or bronze) door handle[1] is undoubtedly the most striking feature of this set. Found on apartment doors, it is fixed in place and is only used to pull the door shut by slamming it.

The Castel Béranger portfolio presents it from several angles.

Like other common models of this type, it consists of three parts: first, a plate that is screwed onto the door and includes a threaded rod; second, a rosette with a hole in the center that overlaps the plate; and finally, a handle whose thread screws onto the rod of the plate before being locked in place by a through pin. The shape of this handle is complex, halfway between a knob, which it resembles in its compact form, and a lever, which it resembles in its distal end. At first glance, it seems less easy to grip than porcelain doorknobs, which do not have finger indentations, but whether placed upwards or downwards, its distal end fits perfectly between the thumb and index finger. Depending on the model, the F.T mark can be found on the plate or on the back of the rosette, where the number 630 also appears.

This landing handle was also present on the entrance door of the Castel Henriette in Sèvres (now destroyed).

Guimard also used it a little later for the doors of apartments in another apartment building: the Jassedé building (1903-1905) at 142 Avenue de Versailles in Paris, where it seems to have made its last appearance.

At Castel Béranger, they suffered the same fate as the porcelain knobs on the interior doors: they were stolen and resold. Those found in private collections, and which occasionally appear on the art market therefore mainly come from this building, where they were replaced by copies around 2000. The Cercle Guimard has also reissued a few of them in bronze, with the function of a door handle rather than a fixed knob.

Also at Castel Béranger, Guimard installed brass (or bronze) door handles[2] in two different models, left and right, which are significantly different, on some of the doors in the common areas. The Fontaine M portfolio provides a beautiful photographic reproduction of these handles.

The Castel Béranger portfolio also provides a view of each model.

The right handle can be found in the series of photographs donated by Adeline Oppenheim-Guimard to the Bibliothèque des Arts Décoratifs in 1948.

Guimard seems to have made relatively little use of these door handles. However, the left-hand model can be found on the front door of the Coutolleau store in Angers in 1897. The right-hand model was probably on the inside.

Similarly, these two models of handles were placed on either side of the front door of the Coilliot house in Lille (1898-1900).

These door handles are therefore much rarer than porcelain doorknobs, but a few have appeared on the art market and may have been purchased.

The Cercle Guimard has also reproduced a few bronze copies of the right handle.

The brass (or bronze) lock model[3] used at Castel Béranger is little known. However, it was present on the upper and lower parts of many double doors in the building’s apartments.

The Castel Béranger portfolio details the various components: upper bolt knob (9), lower bolt knob (10), rod guide (11), upper strike plate (12), strike plate (13)

There are actually two different models: an upper lock,

and a lower lock. The plate and rod guide are common to both locks, while their knobs are different and only the upper lock has a strike plate (the lower lock’s strike plate is a simple metal plate screwed to the floor).

Curiously, the Fontaine M portfolio features a lower lock with an upper strike plate.

These locks were most likely used by Guimard on buildings contemporary with or slightly later than the Castel Béranger. We know this for certain in the case of the Castel Henriette and the Castel Val in Auvers-sur-Oise.

The espagnolette systems at Castel Béranger were also produced by Fontaine in large numbers, as they were used on all the windows, both interior and exterior, of the building. The rods are half-round with a width of 16 mm.

As shown in the Fontaine M portfolio plate, their components were cast in two materials with different appearances and costs: cast iron and brass (or bronze)[4]. It is likely that the brass versions were intended for windows in reception rooms such as living rooms (below). The cast iron versions, intended to be painted, were probably relegated to other areas.

However, brass handles are often found on cast iron systems, without it being possible to know whether they were originally placed there or whether they have been moved since.

When the components of the espagnolette systems are made of cast iron, their finish is unusually refined.

These espagnolette systems were most likely used by Guimard on buildings contemporary with or slightly later than the Castel Béranger. We know this to be true for the Castel Henriette and the Castel Val.

For the restoration of Castel Béranger in 2000, copies were made by the Rollinger foundry in Nouvion-sur-Meuse to replace the missing espagnolette systems.
The Cercle Guimard also reissued a few copies in bronze.

Notes
[1] The Castel Béranger portfolio lists them as copper, while the Fontaine M portfolio lists them as bronze. In the field of hardware, differences and confusion between the names of these alloys, whether commercial, customary, or scientific, are very common.

[3] The Castel Béranger portfolio lists them as copper, while the Fontaine M portfolio lists them as bronze. Observation of an old model shows traces of gilding. The back plate of the lock is brass, and the half-round rods and bolts are iron.
[4] The Castel Béranger portfolio does not indicate the type of metal, while the Fontaine M portfolio lists them as bronze or cast iron.
