Julian Nelson Frank (1906–1974) was a journalist, anti-communist, a special agent with U.S. Naval Intelligence, an investigator for the Senate Internal Security Subcommittee, and a bookstore owner. He was a writer, labor editor, and columnist for the New York World-Telegram from 1944 to 1955, where his 1945 article concerning the Duclos letter, which contributed to the ouster of Communist Party USA head Earl Browder, was nominated for a Pulitzer Prize. Frank also wrote for Life and Fortune.
Frank's front-page World-Telegram expose' did much to popularize the story of "Red Spy Queen" Elizabeth Bentley; he appeared with her on one of the first episodes of Meet the Press. A former communist who had worked for The Daily Worker, Frank testified before Rep. Richard Nixon and HUAC to support Whittaker Chambers's accusations against Alger Hiss.
Frank was the father of Johanna Hurwitz and the grandfather of Garance Franke-Ruta and Ted Frank.
