    Clifford Wiens

    Clifford Donald Wiens, architect, designer, teacher (born 27 April 1926 in Glenn Kerr, SK; died 25 January 2020 in Vancouver, BC). Clifford Wiens’s distinguished body of work reflects both corporate modern architecture and a broader expressionist movement. Wiens was known for his superb and inventive architectural and structural details, as well as for his simple but strong forms. His distinctive approach to structure and form was shaped by his relationship with the abstract painters in the Regina Five and his background in industrial design. Wiens won two Massey Awards and the Prix du XXe siècle from the Royal Architectural Institute of Canada. Following his death in 2020, the Globe and Mail called him Saskatchewan’s “leading architect of the postwar era.”
