About
Roy Marcus Cohn (February 20, 1927–August 2, 1986) was an infamous American attorney and political fixer, born in the Bronx, New York, to a prominent legal family; his father, Albert C. Cohn, served as a justice on the New York Supreme Court. Demonstrating exceptional academic ability, Cohn entered Columbia College at age 14 and graduated from Columbia Law School by age 20 in 1947, gaining admission to the bar shortly thereafter despite some accounts noting a lack of a formal undergraduate degree. He quickly rose in the U.S. Attorney's office for the Southern District of New York, specializing in subversive activities during the Second Red Scare, and gained national notoriety as the youngest prosecutor in the 1951 trial of Julius and Ethel Rosenberg, aggressively pushing for their conviction and execution for espionage in 1953. Cohn then joined Senator Joseph McCarthy's staff as chief counsel, playing a key role in anti-communist investigations that culminated in the televised Army-McCarthy hearings of 1954, leading to McCarthy's censure and Cohn's departure from Washington. Returning to New York, Cohn built a lucrative private practice representing mob figures like Tony Salerno and Carmine Galante, real estate developers, and celebrities, often employing ruthless tactics including allegations of perjury and witness tampering, which contributed to disbarment proceedings against him in 1986, just before his death from AIDS-related complications. Holding dual U.S.-Israeli nationality, Cohn was known for his conservative political influence, aggressive legal strategies, mentorship of Donald Trump and Roger Stone, and ventures including authoring books and business dealings.
