Early life and education

Born to an affluent Jewish family in the Bronx, New York City, Cohn was the only child of Dora (née Marcus)^[7] and Justice Albert C. Cohn; Cohn's father was an assistant district attorney of Bronx County at the time, and was later appointed as a judge of the Appellate Division of the New York State Supreme Court.^[8][1] His maternal great-uncle was Joshua Lionel Cowen, the founder and long-time owner of the Lionel Corporation, a manufacturer of toy trains.^[9] A botched pediatric surgery to modify the appearance of his nose left Cohn with a prominent scar.^[10]

Cohn and his mother were close; they lived together until her death in 1967 and she was constantly attentive to his grades, appearance and relationships.^[11] When Cohn's father insisted that his son be sent to a summer camp, his mother rented a house near the camp and her presence cast a pall over his experience. In personal interactions, Cohn showed tenderness which was absent from his public persona, but he was vain and deeply insecure.^[11]
