Manitoba Business: Waisman Ross and Associates / Blankstein Coop Gillmor and Hanna / Number TEN Architectural Group

In May 1953, the Winnipeg-based architectural firm of Waisman Ross and Associates was established by Allan Harvie Waisman and Jack Mollison Ross. It merged in 1964 with the firm of Blankstein Coop Gillmore and Hanna that had been founded in 1956 by Morley Blankstein and Isadore “Issie” Coop (joined in 1959 by Alan Hanna and R. Douglas Gillmor). The combined name proved cumbersome so it soon became Number TEN Architectural Group, named for the number of its office on Donald Street.
