Marcel Breuer (1902–1981) was a Hungarian-born architect and furniture designer, a key figure in the International Style. Educated at the Bauhaus, he innovated with tubular steel furniture like the Wassily and Cesca chairs. Moving to the U.S. in 1937, he partnered with Walter Gropius and later designed iconic buildings such as the Whitney Museum of American Art in New York and UNESCO Headquarters in Paris. His work spans from modernist homes to large public buildings, blending new materials and industrial techniques with functional design principles​.
