Biography
John G. Weiler was a member of the Communist Labor Party convicted under California's Criminal Syndicalism Act and sentenced to an indeterminate term of one to fourteen years. He was confined at San Quentin State Prison from February 1921 and paroled in May 1923.
The case concerned Communist Labor Party organisation or membership. An earlier version of this record classified it as a federal Espionage or Sedition Act prosecution, which it was not.
His documented custody span is roughly two years and three months, calculated from month-only dates rather than from any statement of time served.
