1906-1965. US sculptor and painter, whose work made a lasting impact on sculpture after World War II. He trained as a steel welder in a car factory. His pieces are large openwork metal abstracts. Smith turned first to painting and then, about 1930, to sculpture. Using welded steel, he created abstract structures influenced by the metal sculptures of Picasso. In the 1940s and 1950s he developed a more linear style. The Cubi series of totemlike abstracts, some of them painted, was designed to be placed in the open air.
