A native of New York City, and son of painter Joseph Hirsch. His father was of German-Jewish descent.[4] After graduating from Columbia in 1966,[5] he began to pursue a career in editing. In the late 1960s, while editing trailers in NYC, he was introduced by his brother, Charles, to then unknown filmmaker Brian De Palma. Their collaboration has yielded eleven feature films. [6]
Hirsch rarely watches movies other than his own more than once. However, he cites that the musical An American in Paris and the science fiction film 2001: A Space Odyssey are worthy of repeat viewing.[7]
