Kahn collaborator Tyng gets her due in Institute of Contemporary Art exhibit

Louis Kahn was considered a pretty good modern architect in 1945 when Anne Griswold Tyng went to work in his office, then located in the Evening Bulletin building across from Philadelphia's City Hall. By the time they parted company two decades later, Kahn was revered for liberating architecture from its Bauhaus straitjacket and Tyng was known, if she was known at all, as his mistress.
