Jacques Godefroy de Tonnancour was an important Quebec and Canadian Contemporary painter, born in Montreal in 1917. He studied at the École des Beaux-Arts de Montréal from 1937 to 1940. His early works in Laurentian landscapes were heavily influence by Goodridge Roberts. He spent seventeen months (1945-46) working in Brazil. Upon his return to Canada, he temporarily abandoned painting landscapes and turned to still life and figurative paintings, influenced by Pellan, Borduas and Picasso.|
Jacques de Tonnancour began teaching at the Musée des beaux-arts de Montréal in 1943, then at the École des Beaux-Arts de Montréal in 1954 as well as at the Université du Québec from 1969 to 1982.
