Spoleto Chairs by Ufficio Tecnico for Knoll, Italy, 1970s

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.

As a company that produced many of the most famous and iconic furniture designs of the 20th century, Knoll was a chief influence in the rise of modern design in the United States. Led by Florence Knoll, the firm would draw stellar talents such as Ludwig Mies van der Rohe and Eero Saarinen into its compass. Their work would help change the face of the American home and office.

The company was formed in 1938 by the German immigrant Hans Knoll. He first worked with his fellow ex-pat, the Danish designer Jens Risom, who created furniture with flowing lines made of wood. While Risom served in World War II, in 1943 Knoll met his future wife, Florence Schust. She had studied and worked with eminent emigré leaders of the Bauhaus, including Mies, Walter Gropius and Marcel Breuer. She won Knoll over with Bauhaus notions of industrial arts, and an aesthetic that featured flat and tubular metal frames and angular forms. When Hans died in a car crash in 1955, Florence Knoll was appointed head of the company. It was as much through her holistic approach to design — a core division of the firm was dedicated to planning office systems — as Knoll's mid-century modern furnishings themselves that she brought about the sleek and efficient transformation of the American workplace.

Today, classic Knoll furnishings remain staples of modern design collections and decor. A history of modern design is written in pieces such as the elegant Barcelona chair — created by Mies and Lilly Reich — Saarinen’s pedestal Tulip chair, Breuer’s tubular steel Wassily lounge chair and the grid-patterned Diamond chair by Harry Bertoia.

As you can see from the collection of these designs and other vintage Knoll dining chairs, sofas and tables on 1stDibs, this manufacturer's offerings have become timeless emblems of the progressive spirit and sleek sophistication of the best of modernism.
