born June 14, 1922, Dublin, Ire.
Irish-born U.S. architect.
After studying under Ludwig Mies van der Rohe , he became Eero Saarinen 's principal design associate. After Saarinen's death in 1961, Roche and John Dinkeloo (1918–81) completed Saarinen's unfinished projects, including the Dulles International Airport Terminal Building, near Washington, D.C. (1962), and St. Louis's Gateway Arch (1965). The two launched their own firm in 1966; their approach, though similar to Saarinen's, resulted in simpler geometric forms. Well-known works by Roche and Dinkeloo include the Ford Foundation headquarters in New York City (1968), General Foods headquarters in Rye, N.Y. (1977), and the Bouygues world headquarters outside Paris (1983). Roche received the Pritzker Architecture Prize in 1982.
