William Bruce Dendy, Canadian architectural historian, was born in Edmonton, Alberta in 1948 and died May 29, 1993 in Toronto, Ontario. Dendy graduated from the University of Toronto in 1971, received a B.A. in Architectural History from Cambridge University in 1973, and in 1979 received two Masters degrees in architectural history, one from the University of Cambridge, and one from Columbia University in New York. He worked as an architectural historian for the Toronto Historical Board from 1973 until 1976, taught Canadian architectural history at the University of Toronto, at the University of Waterloo, at Carleton University in Ottawa, at Ryerson Polytechnic Institute in Toronto, and at the Toronto Urban Studies Centre. Dendy also worked on a consultancy basis as architectural historian to many Toronto-based architectural firms, developers, and government agencies, and also led architectural walking tours of Toronto.

Dendy's two published works, Lost Toronto (1978) and Toronto Observed: Its Architecture, Patrons, and History (1986), were both published by the Oxford University Press and both won Toronto Book Awards. In 1993 Dendy was awarded an honorary membership in the Ontario Association of Architects, and in the same year he was given an Allied Arts Award for his lectures and books on historical architecture.
