Henrietta Mary Shore was a Canadian-born artist who was a pioneer of modernism. Between 1900 and 1913 Shore travelled back and forth between Toronto, Europe and New York. It was during this period that she enrolled in the New York School of Art and studied under William Merritt Chase and Robert Henri, often spending half the year in New York. Henri's Ash Can School aesthetic influenced Shore's work during this time. In 1913 Shore moved from Toronto to Southern California, settling in Los Angeles and becoming part of a small but influential group of early West Coast modernists. In 1927 Shore was introduced to photographer Edward Weston. Her paintings of sea shells attracted and influenced him and he borrowed some of her shells for his photographs.[On Weston's urging, Shore travelled to Mexico and it was there that she was introduced to lithography, a medium which she continued to work in upon her return to California.
