Louis I. Kahn was born in Estonia and raised in Philadelphia. He was trained in architecture in the Beaux-Arts tradition at the University of Pennsylvania under Paul Philippe Cret. As a mature architect, Kahn was distinguished from his contemporaries (in a period dominated by the International Style) by his unique personal philosophy of architecture and a style marked by a profound sense of history and pure geometry in design and the texture of materials in construction. His legacy is as much in his teaching and his unbuilt designs as in his major built works. He lectured and wrote on architecture beginning in the 1930s. He taught at Yale University (1947-1955) and was Cret Professor of Architecture at the University of Pennsylvania from 1956 until his death.
