The story

Founded by Donald Schmitt and Jack Diamond in 1975.1

History

Diamond was the founding director of the University of Toronto's Master of Architecture program. Diamond worked closely with Barton Myers, an American and Canadian architect, and is currently the president of Barton Myers Associates Inc. Myers established his own practice with Diamond in Toronto in 1968. Starting this year, the architects founded their new firm Diamond and Myers. The two eventually split in 1975. Diamond Schmitt Architecture would not officially begin until 1974 when Jack Diamond established his own firm, A.J Diamond Architects.

It was around this time that the partnership between Jack Diamond and Donald Schmitt began. Schmitt studied architecture at the University of Toronto where Diamond had worked, continuing his education until 1978. After thirteen years of A.J. Diamond Architects, in 1989, the firm had developed further when Jack Diamond partnered with Schmitt.

Founding

Abel Joseph "Jack" Diamond was born in 1932 in South Africa, and had arrived in Canada in 1964, the same year he started working for the University of Toronto. In 1970, Diamond had begun renovating a ceramics manufacturing plant, and adding living spaces on one of the floors. Five years later, Diamond established his company A.J Diamond architects, and three years later he would form his partnership with Donald Schmitt and Company.

Donald Schmitt was born 1951 in South Porcupine, a small mining town in northern Ontario. He went to high school at the University of Toronto Schools (UTS) and studied afterwards at the University of Toronto's Faculty of Architecture.

Apart from the firm's founding principals, there are also 19 other principals, 12 senior associates, 37 associates, 8 directors, 129 registered graduates and student architects, and a support staff of 43.
