Harry Horowitz ( – April 13, 1914), also known as "Gyp the Blood", was an American underworld figure and a leader of the Lenox Avenue Gang in New York City. Early life and career Harry Horowitz was born on the Lower East Side of Manhattan to Orthodox Jewish parents. He was a slight figure, standing just under and weighing . but extraordinarily strong.
