15. Walter Gropius
Walter Gropius is another significant founder of modern architecture. Gropius (1833-1969) was not only a renowned German architect but also the founder of Bauhaus Art School. The winner of AIA Gold Medal in 1959, Gropius is remembered now not only for the various buildings he designed but also for the entire Gropiustadt district in Berlin. He combined a practical approach to materials with a unified vision for more modern and simple structures. Among his most important pieces of works are the Fagus Factory in Saxony, the University of Baghdad in Iraq, John F. Kennedy Federal Building in Boston, and Werkbund Exhibition in Cologne.
