Robert Delaunay was a French artist born in 1885 who had no formal art training. He became interested in Cubism and helped develop Orphism, an abstract art movement using bright colors and geometric shapes. One of his most famous works from 1912, Simultaneous Windows on the City, showed his style of bold colors and geometric forms influenced by Cubism. Later in his career, he created large murals for the 1937 World's Fair that were inspired by modern transportation.
