Marcel Breuer (1902–1981) was a Hungarian-born architect and designer and one of the most influential figures of modernism. Trained at the Bauhaus, where he later became head of the furniture workshop, he pioneered the use of tubular steel in furniture design, transforming an industrial material into something light, rational and unexpectedly elegant, most famously with the Wassily and Cesca chairs. His work balanced clarity of structure with functional precision, reflecting the Bauhaus belief that design should unite art, craft and technology. In later decades, Breuer expanded his practice into architecture, creating powerful concrete buildings that carried the same sense of geometry and structural honesty that defined his furniture, leaving a legacy that shaped both modern interiors and city skylines.
