Walter Gropius (1883-1969) was a German architect and founder of the Bauhaus school, renowned for modern architecture alongside figures like Le Corbusier and Frank Lloyd Wright. He served in World War I and later transformed the Grand-Ducal Saxon School of Arts and Crafts into the influential Bauhaus in 1919, which integrated art, craft, and industrial design. Gropius's innovative designs emphasized functionality, aesthetics, and the use of modern materials, with notable works including the Gropius House in Massachusetts and the Bauhaus building in Dessau.
