Claude Tousignant, OC (born December 23, 1932 in Montreal, Quebec) is a Canadian artist. Tousignant is considered to be an important contributor to the development of geometric abstraction in Canada. Tousignant is considered a member of the second generation of the modern art movement in Montreal called “les Plasticiens”. This group of four painters (Jean-Paul Jérôme, Louis Belzile, Rodolphe de Repentigny and Fernand Toupin) felt painting should be pure form and colour; meaning and spontaneous expression were to be avoided. In 1962, Tousignant introduced the form of the circle, which would become his signature motif, into his geometric paintings.
