Jack Bush

John Hamilton "Jack" Bush (20 March 1909 – 24 January 1977) was a Canadian abstract painter. His paintings are associated with the Color Field movement and Post-painterly Abstraction.

Bush was born in Toronto, Ontario, in 1909. As a young man, he studied with Adam Sheriff Scott and Edmond Dyonnet in Montreal, Quebec.

In his early stages, Bush was influenced by the work of Charles Comfort and the Group of Seven. During the 1940s, he ran a commercial art business and, by night, furthered his studies at the Ontario College of Art. Bush, like other Canadian artists of the time, was sheltered from major European influences. After seeing the work of the American Abstract Expressionists in New York City, Bush's canvases changed dramatically.

Bush developed his work and approach to abstraction through the 1950s. He was a member of Painters Eleven, the group founded by William Ronald in 1953 to promote abstract painting in Canada, and was soon encouraged in his art by the American art critic Clement Greenberg. Critical at first, Greenberg became a mentor to Bush and encouraged him to refine his palette, technique, and approach. As a result of Greenberg's guidance, Bush became closely tied to Color Field Painting. Bush became friends with artists associated with color-field like Jules Olitski, Kenneth Noland and also Anthony Caro. As Painters Eleven disbanded in 1960, Bush moved on, and in the end became one of the more successful artists to come from this group.
