Biography
Harry Canter (Harry J. Canter, also recorded as Harry Kantor) was prosecuted for criminal libel after carrying a placard blaming Governor Alvan Fuller for the executions of Sacco and Vanzetti at a Boston demonstration on November 3, 1928. Convicted on May 27, 1929, he received a one-year hard-labor sentence and served at Deer Island. He was physically released from Deer Island on April 22, 1930, as reported by the next day’s Daily Worker from the welcoming parade at the dock.
Daily Worker, June 14, 1929, page 1–2: Karl Reeve’s June 13 Boston prison interview establishes actual Deer Island confinement under the one-year term for the anti-Fuller Sacco–Vanzetti placard. Canter described seven-day kitchen work of thirteen to fourteen hours daily, peeling vegetables, cleaning kettles and floors, sleep disturbance, no exercise periods, restricted visits and two one-page letters monthly. Reeve obtained special visitor permission. Canter’s appeal to free Gastonia prisoners is a prison statement, not a new arrest or an early release. Judge John Hannon, mentioned for favorable treatment, was an ordinary theft prisoner and is not added as a political prisoner.

The June4,1930 Daily Worker reports that Harry J. Canter, recently released from Deer Island, had been nominated for governor. Its rounded reference to a year’s sentence does not replace the separately established April22 physical release or establish a second jail interval.

His published May 30, 1929 sentencing statement defends the anti-Fuller placard as a protest over the Sacco–Vanzetti executions and rejects any retraction. The Daily Worker says the judge interrupted and sheriffs removed him; ILD secretary Juliet Stuart Poyntz announced an appeal and protests, which were prospective. The introduction dates the original demonstration November 3, agreeing with the court record. This does not alter his independently established April 22, 1930 physical release.

The May 15 account describes preparations for his scheduled May 16 trial and the effort to subpoena former Governor Fuller. These are defense and pending-trial details, not a completed judgment or new detention. His independently recorded May 30 sentence and April 22, 1930 release remain distinct.

1920s custody review: The Massachusetts Supreme Judicial Court records the placard demonstration and associated arrest on November 3, 1928, indictment on December 10, and guilty verdict on May 27, 1929. The Daily Worker of May 31, 1929 reports his sentencing statement in court the previous day and a one-year hard-labor sentence. Its June 4, 1930 report, datelined Boston June 3, says he had just been released from Deer Island after serving the year. The 1929 prison admission remains at year precision. These earlier-reviewed reports did not establish the exact discharge day; the April 23, 1930 issue subsequently reviewed reports his actual April 22 release from Deer Island and the welcoming parade at the dock. Release is now recorded as April 22, 1930; June 3 or June 4 is not substituted as his release date. The court record and the original May 31 newspaper statement introduction both date the demonstration November 3, 1928. The earlier description of the newspaper introduction as November 4 was a transcription error. Earlier pretrial bail is distinct from the subsequent prison term.
