Sidney Bregman (born 9 April 1922 in Warsaw, Poland; died 9 February 9 2014 in Toronto, ON) and George Frederick Hamann (born 14 June 1928 in Toronto, ON; died 9 February 2013 in Newmarket, ON), architects.

The Bregman + Hamann Architects firm, founded in Toronto in 1953, is active across North America primarily in the design and construction of health-care facilities (Mount Sinai Hospital, Toronto, and the Ottawa General Hospital) and of commercial and retail space.
Alone or in joint venture, the firm has designed over 2.8 million square metres of office accommodation, much of it in downtown Toronto: the Toronto-Dominion Centre with the firm John B. Parkin Associates (see John Burnett Parkin) and German-American architect Ludwig Mies van der Rohe; the Eaton Cenre with Zeidler Partnership (Eberhard Zeidler); Harbour Square on the city’s waterfront; the Simpson Tower, again with John B. Parkin Associates, completed in 1968; and the 72-storey First Canadian Place in collaboration with the American architect Edward Durell Stone.

George Frederick Hamann retired from the firm in 1987.
The firm won an Award of Excellence (Innovation in Architecture) from the Royal Architectural Institute of Canada (RAIC) in 2005 for Queen's University’s Beamish-Munro Hall in Kingston, Ontario.
The firm changed its name to B+H Architects (or simply BH Architects) and is now a member of the Surbana Jurong (SJ) Group.
