Biography
Jack Garvine was listed among the class-war prisoners on the International Labor Defense's 1930 Winter Relief roster, confined at the Deer Island Prison in Boston, Massachusetts.
The September 8, 1930 Laisve, page 5, reproduces an International Labor Defense political-prisoner directory. Its row prints Jack Garvine, no term or sentencing year supplied, and confinement or correspondence location Deer Island, Boston Harbor, Boston, Massachusetts. This is an attributed historical directory entry; printed years and nominal terms are not exact intake dates or measured time served, and mailing boxes do not independently identify a prison. The directory contains stale or conflicting chronology, so this row does not override independently established conviction, death or release facts.
