Pair of Marcel Breuer Cesca Chairs by Gavina for Knoll

The architect and designer Marcel Breuer was one the 20th century’s most influential and innovative adherents of modernism. A member of the Bauhaus faculty, Breuer — like such colleagues as the architects Walter Gropius and Ludwig Mies van der Rohe, and the artists and art theoreticians László Moholy-Nagy and Josef Albers — left Europe in the 1930s to champion the new design philosophy and its practice in the United States.

Born in Hungary, Breuer became a Bauhaus student in 1920 and quickly impressed Gropius, the German school’s founder, with his aptitude for furniture design. His early work was influenced by the minimalist Dutch design movement De Stijl — in particular the work of architect Gerrit Rietveld.

In 1925, while he was head of the Bauhaus furniture workshop, Breuer realized his signature innovation: the use of lightweight tubular-steel frames for chairs, tables and sofas — a technique soon adopted by Mies and others. Breuer’s attention gradually shifted from design to architecture, and, at the urging of Gropius, he joined his mentor in 1937 on the faculty of Harvard and in an architectural practice.

In the 1940s, Breuer opened his own architectural office, and there his style evolved from geometric, glass-walled structures toward a kind of hybrid architecture — seen in numerous Breuer houses in New England — that pairs bases of local fieldstone with sleek, wood-framed modernist upper floors. In his later, larger commissions, Breuer worked chiefly with reinforced concrete and stone, as seen in his best-known design, the brutalist inverted ziggurat built in New York in 1966 as the home of the Whitney Museum of American Art.

Breuer’s most famous furniture pieces are those made of tubular steel, which include the Wassily chair — named after Wassily Kandinsky and recognizable for its leather-strap seating supports — and the caned Cesca chair.

Breuer also made several notable designs in molded plywood, including a chaise and nesting table for the British firm Isokon and a student furniture suite commissioned in 1938 for a dormitory at Bryn Mawr College. Whether in metal or wood, Breuer’s design objects are elegant and adaptable examples of classic modernist design — useful and appropriate in any environment.

Architect, furniture designer, interior designer, entrepreneur — Florence Knoll had a subtle but profound influence on the course of mid-century American modernism. Dedicated to functionality and organization, and never flamboyant, Knoll shaped the ethos of the postwar business world with her skillfully realized office plans and polished, efficient designs for sofas, credenzas, desks and other furnishings.

Knoll had perhaps the most thorough design education of any of her peers. Florence Schust was orphaned at age 12, and her guardian sent her to Kingswood, a girl’s boarding school that is part of the Cranbrook Educational Community in suburban Detroit. Her interest in design brought her to the attention of Eliel Saarinen, the Finnish architect and head of the Cranbrook Academy of Art.

Saarinen and his wife took the talented child under their wing, and she became close to their son, the future architect Eero Saarinen. While a student at the academy, Florence befriended artist-designer Harry Bertoia and Charles and Ray Eames. Later, she studied under three of the Bauhaus masters who emigrated to the United States. She worked as an apprentice in the Boston architectural offices of Walter Gropius and Marcel Breuer; Ludwig Mies van der Rohe taught her at the Illinois Institute of Technology.

In 1941, she met Hans Knoll, whose eponymous furniture company was just getting off the ground. They married in 1946, and her design sense and his business skills soon made Knoll Inc. a leading firm in its field. Florence signed up the younger Saarinen as a designer, and would develop pieces by Bertoia, Mies and the artist Isamu Noguchi.

Florence Knoll's main work came as head of the Knoll Planning Group, designing custom office interiors for clients such as IBM and CBS. The furniture she created for these spaces reflects her Bauhaus training: the pieces are pure functional design, exactingly built; their only ornament from the materials, such as wood and marble. Her innovations — the oval conference table, for example, conceived as a way to ensure clear sightlines among all seated at a meeting — were always in the service of practicality.

Since her retirement in 1965, Knoll received the National Medal of Arts, among other awards; in 2004 the Philadelphia Museum of Art mounted the exhibition “Florence Knoll: Defining Modern” — well deserved accolades for a strong, successful design and business pioneer. As demonstrated on these pages, the simplicity of Knoll’s furniture is her work’s great virtue: they fit into any interior design scheme.
