A major retrospective of Umberto Boccioni's work happened in 1988 at The Metropolitan Museum of Art in New York City. Boccioni was an Italian Futurist painter, sculptor, and theorist. He was one of the most influential figures in the early development of abstract art. His paintings often depicted scenes of modern life, such as cityscapes and industrial landscapes. He was also a pioneer in the use of collage and assemblage.
