Born in Ancona, Italy, Pietro Belluschi received a degree in engineering from the University of Rome in 1922, followed by a degree in civil engineering from Cornell University in 1924. By 1925, however, he had relocated to Portland, OR, where he would eventually establish a practice that would receive international attention. Beginning as a designer in the office of Albert E. Doyle, Belluschi remained with the office, reorganizing it under his own name in 1943. Later Belluschi would teach at the Massachusetts Institute of Technology and would receive the Gold Medal of the AIA in 1972.
Although Belluschi is chiefly known as a Pacific Northwest architect, his buildings are scattered over the United States, including Temple B'nai Jeshurun (in association with Grunzen & Partners), Short Hills, NJ (1964-68) and the IBM Center (in association with Emery Roth & Sons), Baltimore, MD (1970-75). In Philadelphia he designed the Univerisity Lutheran Center on the University of Pennsylvania campus, and he participated occasionally in the annual Philadelphia Chapter AIA exhibitions.
