Marcel Lajos Breuer (1902 – 1981) was a Hungarian-German modernist architect and furniture designer. Breuer extended the sculpture vocabulary he had developed in the carpentry shop at the Bauhaus into a personal architecture that made him one of the world's most popular architects at the peak of 20th-century design. His work includes art museums, libraries, college buildings, office buildings, and residences. Many are in a Brutalist architecture style, including the former IBM Research and Development facility which was the birthplace of the first personal computer. He is regarded as one of the great innovators of modern furniture design.
