Biographical Information [+]
Marcel Lajos Breuer was born on May 21, 1902, in the Danube valley town of Pécs, Hungary, to Jacques Breuer, a physician, and Franciska (Kan) Breuer. His siblings were Hermina and Alexander. Throughout his life, Breuer used his first name only on official documents and preferred that his friends use his middle name, the Hungarian form of "Louis." The diminutive form of this name was usually spelled "Lajkó" and pronounced "Lye-ko." READ MORE
In 1920, Breuer graduated from the Magyar Királyi Föreáliskola in Pécs. He had received a scholarship to study art in Vienna but took an immediate dislike to the Art Academy there, so searched elsewhere for training. He started working in the studio of a Viennese architect and soon became interested in training in the cabinetmaking shop of the architect's brother. Breuer was not satisfied with this arrangement either, and, upon hearing about the year-old Bauhaus school in Germany, he departed for Weimar in 1921.
Founded and directed by Walter Gropius, the Bauhaus combined the teaching of the pure arts with training in functional technology. Breuer received a master's degree from the Bauhaus in 1924, then studied architecture in Paris, where he first met Le Corbusier.
In 1925, Gropius enticed Breuer to return to the Bauhaus, now relocated in Dessau, by offering him a post as master of the carpentry workshop and a commission to design the interiors of the new Bauhaus buildings. Inspired by his new bicycle's handlebars, Breuer designed his first tubular steel chair, the Wassily chair, named for his friend Wassily Kandinsky. This chair and dozens of other Breuer designs for furnishings were mass-produced by the Thonet Brothers in Germany.
Two years later, in 1928, Breuer left the Bauhaus to begin a private architecture practice in Berlin, emphasizing prefabricated housing and the use of concrete in building. During this time Breuer worked on a designs for the Potsdamer Platz, Spandau-Haselhorst Housing, and a hospital in Elberfeld, and he completed work on the Lewin House and the Harnischmacher Apartment. Due to the deteriorating economic and political conditions in Germany, Breuer closed his Berlin office in 1931 and traveled to Budapest, Zurich, Morocco, Greece, and Spain. Returning to Germany in the following year, he began designing furniture in aluminum. Breuer established his reputation as an architect upon completion of the Harnischmacher House in Wiesbaden, a house notable for the use of contrasting materials and distinctive interiors.
The Nazis closed the Bauhaus in 1933. The following year, Breuer designed the Dolderthal Apartments in Zurich for the Swiss architectural historian Sigfried Giedion. From 1935 to 1937, Breuer settled in London, and became partners with F. R. S. Yorke. During this time he designed for the Isokon ("isometric unit construction") Control Company laminated plywood furniture that became widely imitated.
In 1937, Breuer accepted an invitation from Walter Gropius to join the faculty of the School of Design at Harvard University to teach architecture, and he moved to the United States. Among his students were Edward Larrabee Barnes, Ulrich Franzen, Philip Johnson, I. M. Pei, and Paul Rudolph. Breuer formed a partnership with Gropius in Cambridge, Massachusetts, from 1937 to 1941. Their firm was engaged primarily in the design of private homes.
In 1946, Breuer moved to New York City, where he established an office in an East 88th Street townhouse. The number of his commissions began to grow slowly, and it was during this time he constructed his own notable residence in New Canaan, Connecticut. He developed the bi-nuclear, or "two-center" house, which was designed to meet the living requirements of modern families by creating functional areas for separate activities.
Breuer's architectural reputation was greatly enhanced when, in 1953, he was commissioned to design, in collaboration with Pier Luigi Nervi and Bernard Zehrfuss, the United Nations Educational, Scientific and Cultural Organization (UNESCO) World Headquarters in Paris. During this year, he also began work on a series of innovative buildings for St. John's Abbey and University in Collegeville, Minnesota.
Between 1963 and 1964, Breuer began work on what is perhaps his best-known project, the Whitney Museum of American Art, in New York City. He also established an office with the name Marcel Breuer Architecte, in Paris, to better orchestrate his European projects. Also during this time, Herbert Beckhard, Murray Emslie, Hamilton Smith, and Robert F. Gatje became partners in Marcel Breuer and Associates. When Murray Emslie left a year later, he was replaced by Tician Papachristou, who had been recommended by Breuer's former student, I. M. Pei.
After several moves to increasingly larger office space in New York, Breuer established his largest office at 635 Madison Avenue and 59th Street in 1965. After suffering the first of a series of heart attacks, Breuer reduced his travel to Europe, eventually leaving the management of the Paris office in the hands of Mario Jossa.
Between 1965 and 1973, Marcel Breuer and Associates continued to receive many diverse and important commissions, including the Department of Housing and Urban Development Headquarters Building (Washington, D.C.), showrooms for Scarves by Vera (New York City), the IBM Corporation (La Gaude, France), the Baldegg Convent (Lucerne, Switzerland), Bryn Mawr School for Girls (Baltimore, Maryland), a third power plant for the Grand Coulee Dam, the Australian Embassy (Paris, France), the Armstrong Rubber Company (New Haven, Connecticut), and the State University of New York Engineering Complex (Buffalo). Breuer also designed residences including a second Gagarin House (Litchfield, Connecticut), the Saier House (Glanville-Calvados, France), the Soriano House (Greenwich, Connecticut), and a third Rufus Stillman House (Litchfield, Connecticut).
Due to failing health in 1972, Breuer sold his New Canaan house and moved into Manhattan so he could more easily commute to the office. By 1976, Breuer's health had declined further, and he retired from practice. The name of his firm was subtly changed from Marcel Breuer and Associates to Marcel Breuer Associates, and later to MBA/Architects and Planners.
Marcel Breuer died on July 1, 1981, in New York City.
This chronology below is based on evidence found within the Marcel Breuer Papers. The dating of projects reflects the range of dates encompassed by the files for each project, not the project's actual construction time. Most architectural projects have several equally significant dates from which it is difficult to assign a single date. Significant dates for a building may include the date of groundbreaking, the laying of the cornerstone, or the first opening day. When a project's dates are unknown or uncertain, a question mark in brackets appears at the end of the entry.

Description of the Collection
Overview - Scope and Contents [+]
The Marcel Breuer papers span the years 1920 to 1986 and measure 37.6 linear feet. They consist of biographical material, correspondence, business and financial records, interviews, notes, writings, sketches, project files, exhibition files, photographs, and printed material that document Breuer's career as an architect and designer. This material reflects the prolificacy and diversity of his creations, from tubular steel chairs to private residences, college campuses, factories, department stores, and international, municipal, and corporate headquarters and complexes. READ MORE
The Biographical Material Series contains documents that list or certify significant events or associations attained by Breuer during his career, such as résumés, licenses, and certificates. The number of awards contained in this series attest to the esteem in which he was held by his colleagues.
Breuer's Correspondence Series illustrates the interaction of his various colleagues and the operation of his architectural offices in the execution of their projects, many of which were in progress simultaneously. This series includes letters from Joseph Albers, Jean Arp, Herbert Bayer, Alexander Calder, Serge Chermayeff, Naum Gabo, Sigfried Giedion, Walter and Ise Gropius, Louis I. Kahn, György Kepes, László Moholy-Nagy, Henry Moore, Eero Saarinen, and José Luis Sert.
The Business and Financial Records Series contains documents which reflect Breuer's commercial transactions that do not directly relate to one specific project. Two project books pertain to 36 architectural projects and record their basic physical and financial details, such as site measurements and cost projections. There are also miscellaneous invoices and receipts, and one of Breuer's personal income tax returns.
The Interviews Series contains typescripts of interviews. Of particular interest is the audiotape interview of Breuer, who discusses his early years as a student and his first impressions of the Bauhaus. There are also untranscribed audiotape interviews of his colleagues György Kepes and Harry Seidler, and his patrons Mr. A. Elzas, and the Koerfers, who discuss their business relationships with Breuer.
There are address lists of colleagues and patrons and résumés from architects contained within the series on Notes, while the Writings Series contains typescripts of lectures and articles written by Breuer concerning architecture and its history. Writings by others are about Breuer and his work, including typescripts, galleys, and photographs of architectural and design projects used in the publication of the book Marcel Breuer Buildings and Projects, 1921-1961 by Cranston Jones.
The Sketches Series consists of 3 small, hand-drawn depictions of unidentified floor plans.
The largest and most comprehensive series houses the Project Files, which consist of approximately 300 project files containing letters, legal documents, and photographs that record the planning and execution of many of Breuer's most important architectural projects. These include the UNESCO Headquarters Building (Paris, France), St. John's Abbey and University (Collegeville, Minnesota), the IBM Corporation Research Center (La Gaude, France), the HUD Headquarters Building (Washington, D.C.), the De Bijenkorf Department Store (Rotterdam, The Netherlands), and the third power plant and forebay dam for the Grand Coulee Dam (Washington state). The file for the Whitney Museum of American Art in New York contains an interesting set of photographs of Breuer showing Jacqueline Kennedy through the construction site.
Of equal importance are the additional Project Files for the 100 residences designed by Breuer, including prefabricated houses such as Kleinmetalhaus and Yankee Portables, and commissioned residences such as the two Gagarin Houses (Litchfield, Connecticut), the two Harnischmacher Houses (Wiesbaden, Germany), Koerfer House (Moscia, Switzerland), the Neumann House (Croton-on-Hudson, New York), the Saier House (Glanville-Calvados, France), the Staehelin House (Feldmeilen, Switzerland), the Starkey House (Duluth, Minnesota), and the three Rufus Stillman Houses (Litchfield, Connecticut). There are also files concerning the four houses Breuer designed for himself in Lincoln and Wellfleet, Massachusetts, and in New Canaan, Connecticut.
The Project Files for Breuer's furniture designs are not as comprehensive as those for his architectural creations but contain many photographs of his early conceptions for chairs, tables, desks, cabinets, rugs, and tapestries.
The Exhibition Files Series contains primarily photographs of exhibitions in which Breuer participated. The extent of his participation is sometimes difficult to determine, because it ranged from designing a single chair, designing rooms for an apartment or an entire house specifically to be shown in an exhibition, to designing an exhibition building. Breuer was also the subject of a retrospective exhibition sponsored by the Metropolitan Museum of Art. This traveling exhibition was seen in New York City, Chicago, Paris, and Berlin.
Images contained in the Photographs Series are of Breuer, including one of him in Philip Johnson's house, Breuer family members, and colleagues, including Herbert Bayer, Alexander Calder, Serge Chermayeff, Walter and Ise Gropius, and Matta. Three photograph albums in this series contain more than 1,000 photographs of 59 architectural projects.
The Printed Material Series houses general clippings that concern groups of projects, rather than one specific project. There is also a scrapbook of tearsheets concerning architectural projects, exhibition announcements, and catalogs for others, and miscellaneous press releases and brochures. HIDE
Arrangement and Series Description
The Marcel Breuer papers are arranged into 11 series, based on type of document. Each series, except Project Files, has been arranged chronologically. The Project Files Series has been divided into 19 subseries of related architectual and design project types. The overall arrangement reflects Breuer's original arrangement. Each subseries or file group within is arranged alphabetically according to the surname of an individual, or a location name of a university. The contents of each project file have been arranged according to material type and a chronology that best reflects the progression of the project toward completion.
