Lois' story, borrowed generously from Alan Hess' book Forgotten Modern: California Houses 1940-1970:
Fred Langhorst, originally from Oak Park, Illinois was a Taliesin apprentice from 1931 to 1936. Following his apprenticeship, Langhorst moved to Los Angeles, then San Francisco, where he developed his own practice. He married Lois Wilson in 1939.
Lois (Wilson) Langhorst was a native of Kiowa, Oklahoma, and a graduate of the University of Oklahoma with degrees in architecture in sociology. She also earned a masters degree in architecture from MIT in 1940. In spite of her credentials, Lois Langhorst was not permitted to work in the promunent Bay Area office of William Worchester, as Wurster feared that the presence of a woman in an architectural studio would damage the fragile esprit de corps of his all-male staff.
Lois and Fred opened an office together in 1942, as equal partners, but because Lois was not licensed until 1948, Fred was often credited as architect of record. When Fred was unable to work due to his alcoholism, Lois ran the practice.
Fred maintained his relationship with Frank Loyd Wright through the years, and that relationship is evident in the work. Lois' affinity for fellow Oklahoman Bruce Goff made her sympathetic to the values of organic architecture. Their 1947 residence in Lafayette is typically Usonian, with its sweeping horizontal planes, but without the ornament typical in Wright's work.
