A trained dentist who became an acclaimed sculptor sometimes associated with the New York School of abstract expressionism, Seymour Lipton (1903-1986) achieved international recognition in 1958, when he was awarded a solo exhibition at the Venice Biennale. Lipton taught sculpture at The New School from the 1940s until 1965. The New School Archives holds twenty of his sketches, made between 1960 and 1969, representing ideas for sculptures.
