When Ferguson started teaching at the NSCAD, he removed all the easels in the studio. With NSCAD president
Garry Neill Kennedy, Ferguson helped establish NSCAD as an important centre for conceptual art, noted for his role in the idea of
"the dematerialization of the art object" in
Lucy Lippard's influential history of conceptualism
Six Years: The Dematerialization of the Art Object from 1966 to 1972. Critic Gary Michael Dault describes Ferguson's teaching at NSCAD as a "37-year trajectory...wherein he stubbornly, persuasively tilled the fields of the kind of conceptual art for which the college became primarily known." Ferguson has work in the collection of the National Gallery of Canada.
Museum of Modern Art in New York and the Museum Sztuki, in
Łódź, Poland. In 1972-73 he was a visiting professor at the
California Institute of the Arts. His work has been regularly reviewed in national and international art journals and news media. In 1996, he was the recipient of 1995
Canada Council for the Arts Molson Prize. Ferguson retired from teaching in 2006. His estate is represented by Olga Korper Gallery in Toronto and CANADA in New York. ==References==
