Biography
Harry Winitsky was a leader of the Communist Party from New York City. Harry Winitsky was sentenced to a five- to ten-year prison term for violating the New York anti-anarchy law and served in Clinton Prison and Sing Sing. Winitsky was reportedly betrayed at his trial by Jay Lovestone, another party leader, who accepted the state's offer to drop its prosecution of him on anti-anarchy charges if he testified against Winitsky.
A dated sentence, not an inferred admission
The National Defense Committee’s 1922 account, page 2, explicitly dates Harry Winitsky’s conviction and five-to-ten-year sentence to March 26, 1920. This is a New York criminal-anarchy prosecution, not a federal Espionage/Sedition prosecution. The dated sentencing event does not establish the first day of custody. The 2006 editorial footnote separately describes bail in spring 1922 and a January 7, 1924 pardon; these are different events.
