Dorothy Knowles was born in Unity, Saskatchewan in 1927. She grew up on a farm overlooking a prairie valley and initially had no plans to become a painter, studying biology at the University of Saskatchewan in Saskatoon between 1944 and 1948. At the time of her graduation, a friend persuaded her to enroll in a six-week summer course given by the University of Saskatchewan at Emma Lake. The course was led by Reta Cowley from Saskatoon and James Frederick Finley from the Ontario College of Art. Under their guidance, young Dorothy found a proclivity for art.Upon her return to Saskatoon, she continued to study painting under Eli Bornstein and Nicholas Bjelejac at the University of Saskatchewan between 1948 and 1952. While taking a summer class at the Banff School in 1952, she decided to study art in England, eventually enrolling in the Goldsmith School of Art in London. She was influenced by the National Gallery, where she particularly admired the works of Piero di Cosimo, Piero della Francesca, Veronese, Ucello, and Renoir.In the 1960s, she attended workshops by the American painter Herman Cherry (1961), the critic Clement Greenberg (1962), Kenneth Noland (1963), Jules Olitski (1964), Lawrence Alloway (1965), and Michael Steiner (1969). All of these had varying degrees of influence on her work, changing her style from a heavy impasto favoured by Greenberg to a more fluid technique preferred by Noland. Most importantly, she discovered the importance of working directly from nature. Thus, weather permitted, she worked out of doors, at times producing finished paintings, at times sketches and photographs which she used in the studio.Dorothy was once asked what five factors she believed were vital for a good life. She responded, “I guess my five have been painting, painting, painting, painting, and painting.” (quote source: www.mcmichael.com)
