Jacques de Tonnancour

de Tonnancour died on 13 January 2005, aged 88, in Montreal, Quebec.

de Tonnancour retired from painting in 1982 to concentrate on entomology. In 2002, Les Éditions Hurtubise published Les Insectes. Monstres ou splendeurs cachées written and illustrated by de Tonnacour. The volume won the Prix Marcel-Couture in 2002. An English edition was published in 2002.

In 1958, works by de Tonnancour along with those of James Wilson Morrice, Anne Kahane and Jack Nichols represented Canada at the Venice Biennale. He was made a member of the Royal Canadian Academy of Arts in 1977.

Though he admired Borduas as a painter, he was not in agreement with the political direction of the Automatistes. In 1948, he helped compose the manifesto which Alfred Pellan used to establish the Prisme d'yeux group. "We seek a painting freed from all contingencies of time and place, of restrictive ideology, conceived without any literary, political, philosophical or other meddling which could dilute its expression or compromise its purity" stated a translation of Prisme d'yeux that was published in Canadian Art. This group opposed those who would sign the Refus Global later that year, feeling that painting should not be a political act.
