Dorothy Eisner (1906–1984) was an American artist whose painting style evolved over many years from an early, quite personal, version of 1930s social realism, through a period of abstract expressionism, and culminating over the last twenty years of her life in a bright painterly style that critics saw as fluid, masterfully composed, and expressionistic. Throughout her long career Eisner maintained a consistency that a gallerist summarized as derived from European modernism but also grounded in American painting of her own generation and the generation before her. Born and raised in Manhattan, she traveled widely and is best known for the late work she made while staying in a summer home off the coast of Maine on Great Cranberry Island.
