A pioneer of Czech functionalism, architect, theoretician, and teacher; he is one of the most prominent figures in Czech modern architecture of the interwar period, with its principles of “new architecture,” purity, truthfulness of form, and the belief that architecture is not an art but a “scientifically-based cultural task.” He soon became a harsh critic of excessive façade decoration. Bearing in mind Le Corbusier’s view of the house as a “machine for living,” he designed four houses in Baba (Heřman, Bouda, Vaváček, and Sutnar). He is the author of the palace building on Národní třída in Prague, which he designed for the Czechoslovak Werkbund in 1936, and he was also the Werkbund’s president from 1935. He also presided over the Architects’ Club and was the editor of the functionalist “Stavba” Magazine. He was a professor and later the rector of CTU in Prague.
