Ireland’s most highly regarded architectural émigré is the subject of a new publication and a USA-based exhibition; Ellen Rowley looks at his legacy

Since the early 1960s, he has been at the forefront of architectural design and technology in the dynamic climate of mid to late 20th-century America, developing such projects as the Oakland Museum, California, 1961–8, the Ford Foundation Headquarters, New York, 1963–68 (Fig 2), the Knights of Columbus Headquarters, New Haven CT, 1965–69, or the Union Carbide Corporation Headquarters (Danbury CT, 1976–82).
