Gropper, William, 1897–1977, American painter and cartoonist, b. New York City. Gropper studied painting under Henri and Bellows. Employed as cartoonist by the New York Tribune, he went to work for the Rebel Worker in 1919. He became a leading painter of the 1920s and 30s, his works being primarily concerned with social responsibilities and class inequalities. Gropper is also known for his murals, such as those in the Dept. of the Interior Building, Washington, D.C. The Senate (Mus. of Modern Art, New York City) is characteristic of his bold, satiric style.
