(b New York, 29 June 1916). American architect. He received his BSc (1939) and his MArch degree (1942) from Harvard University, Cambridge, MA. His early work for Marcel Breuer (1942) and Skidmore, Owings & Merrill in New York (1945–8), before founding his own office in 1948, helps explain his unique approach, which he has described as ‘functional expressionism’. His early Warner House (1957), New Canaan, CT, recalls Philip Johnson’s early residences, but his dramatic US Embassy (1963–4), Dublin, Ireland, employed richly moulded precast concrete elements to create an undulating wall. Subsequent buildings were equally dramatic, especially his Clowes Hall (1964; with Evans Woollen), Indianapolis, IN; the Morris Mechanic Theater and the Charles Center (1967), Baltimore, MD; the Goddard Library (1968), Clark University, Worcester, MA; and his Mummer’s Theater (1970–71; now the Oklahoma Theater Center), Oklahoma City, OK. In 1968 he moved his office from New Canaan to New York and two years later formed a partnership with Ashok M. Bhavnani, which focused more on multi-storey housing and academic complexes. Johansen closed his practice in 1970.
