Gorky’s early life was disrupted when his father abandoned Turkey, his wife, and his family in order to avoid service in the Turkish army. The rest of the family soon fled to Armenia to escape Turkish persecution and were subsequently dispersed. In 1920 Gorky emigrated to the United States, where he rejoined his sister in Watertown, Mass., and assumed the pseudonym by which he became known. The name Arshile is derived from Achilles, the brooding Achaean hero of the Iliad. The name Gorky (Russian for “the bitter one”) is derived from that of the writer Maksim Gorky.
But his oeuvre is a phenomenal achievement in its own right, synthesizing Surrealism and the sensuous color and painterliness of the School of Paris with his own highly personal formal vocabulary. His paintings and drawings hang in every major American museum including the National Gallery of Art, the Museum of Modern Art, the Art Institute of Chicago, the Metropolitan and the Whitney Museum of American Art in New York (which maintains the Gorky Archive), and in many worldwide, including the Tate in London.Wikipedia
