In 1953, architects Robert Geddes, Mel Brecher, George Qualls, and Warren “Barney” Cunningham co-founded a collaborative practice, Geddes Brecher Qualls Cunningham: Architects (also known as GBQC Architects), in Philadelphia, later adding an office in Princeton. GBQC won national and international competitions and awards, starting with being runner-up in the Sydney Opera House design competition (1955). Other notable projects include: the Pender Labs at the Moore School of Electrical Engineering at the University of Pennsylvania; the Police Headquarters of the City of Philadelphia; Richard Stockton College in New Jersey; Hill Hall at Rutgers University-Newark; the College of Liberal Arts of Southern Illinois University; the Architects Housing in Trenton, New Jersey; Princeton Community Housing’s Griggs Farm neighborhood; and probably best known, the Dining Hall and Birch Garden quad at the Institute for Advanced Study in Princeton.
