Paffard Keatinge-Clay began his architectural career in the war years, working in Erno Goldfingers office and studying at the AA. He was mentored by Siegfried Giedion (whose daughter he later married). He then worked for Le Corbusier on the Unite dHabitation and for Frank Lloyd Wright on the Johnson Wax building and the Guggenheim Museum. Following a period homesteading in the Arizona desert, Keatinge-Clay found employment as a designer for SOM in Chicago, where he began a close association with Mies van der Rohe. Keatinge-Clays own office opened in San Francisco in 1963 and produced a notable series of modernist masterpieces in the San Francisco Bay area, including the San Francisco Art Institute and the San Francisco State Student Union. This talk traces his remarkable career and explores the work of his own practice, ranging from the 1960s to his current sculptural work.
