I knew metal working before I knew Calder [famous for his sculptures, made in sheet metal], and Calder is one of our great men and he is earlier by a few years than any of the rest of us [in American Abstract Expressionism ]. Calder had worked in Paris quite a bit in the early days, though he did go to school here in New York at the Art Student's League.. .After my first year in college I had worked on the assembly line in the Studebaker plants up in Indiana..
