Input: Consider Input: Question: Was Leon Friend still active as a teacher the year Gorelick graduated from Brooklyn College? Passage:Born Shirley Fishman in Brooklyn, New York, she attended Abraham Lincoln High School. Her teacher, Leon Friend, arranged for guest lectures by commercial and fine artists. Shirley Fishman had the opportunity to study with three of them: Chaim Gross, Moses Soyer, and Raphael Soyer. Gross influenced her early sculptural work, which features squat figures with thick limbs. While attending Brooklyn College, where she earned her B.A. in 1944, she met Leonard Gorelick (1922–2011), a fellow student. They married in 1944 and shared an enthusiasm for art and culture. Leonard Gorelick was an orthodontist and later a collector of cylinder seals. He combined his interests by investigating the authenticity of cylinder seals through the use of dental technology, especially electronmicroscopy. Shirley Gorelick earned an M.A. at Teachers College, Columbia University in 1947. That year, she studied for several weeks with Hans Hofmann in Provincetown. For a short time in the late 1950s, she was a student of the painter Betty Holliday and, in the early 1960s, learned printmaking in the Long Island studio of Ruth Leaf.
