Elizabeth "Betty" Dimock (née Grimmer) pursued painting at the Pratt Institute in New York before pausing her studies to train as a nurse and enlist in the military during World War II. After graduating in 1940, she was stationed in Africa and later England. Following the war, she resumed her passion for art, studying at the Sorbonne before returning to Canada. Settling in Winnipeg, she earned a Bachelor of Fine Arts from the University of Manitoba in 1979.

Dimock worked primarily in watercolours and abstract printmaking, further refining her craft in Japan through summer print workshops. Deeply engaged in Winnipeg’s art community, she served as chair of the Manitoba Society of Artists and exhibited extensively throughout the 1980s and 1990s. In 1983, she was commissioned to paint the Stations of the Cross for a church, further solidifying her artistic legacy.
