George Fred Keck

Keck designed two key model structures for the Century of Progress exhibition in Chicago in 1933; dubbed the "House of Tomorrow". At the time of its construction, the media dubbed the House of Tomorrow as “America’s first glass house.” These two structures played a key role in the development of Keck's form of modernism. In 1934 he designed another model house, "Crystal House", which was directly reminiscent of the work of Ludwig Mies van der Rohe and Marcel Breuer.

Keck became a pioneering designer of passive solar houses in the 1930s and 40s after realizing that the all-glass "House of Tomorrow" was warm inside on sunny winter days prior to the installation of the furnace. Following this he gradually started incorporating more south-facing windows into his designs for other clients, and in 1940 designed a passive solar home for real estate developer Howard Sloan in Glenview, Illinois. The Sloan House was called a "solar house" by the Chicago Tribune, the first modern use of that term. Sloan then built a number of passive solar houses, and his publicity efforts contributed to a significant "solar house" movement in the 1940s.

Keck taught architecture at the New Bauhaus School (now IIT Institute of Design). He was the head of architecture there until 1942 and appointed Ralph Rapson as his successor. Rapson also worked in Keck's office during this period, as did fellow New Bauhaus School professor Robert Bruce Tague.
