Biography
Henry Matlin was imprisoned at San Quentin State Prison in the mid-1920s, during the era of California's criminal-syndicalism prosecutions that sent more than a hundred labor radicals to San Quentin and Folsom. He appears on the International Labor Defense's roster of class-war prisoners in the first issue of Labor Defender (January 1926); like most of the rank-and-file victims of that campaign, little else about his case entered the historical record.
The International Labor Defense holiday roster in the December 29, 1925 Daily Worker lists this prisoner, printed as Henry Matlin, at San Quentin California. Its printed identifier is 35717; this is a prison number or mailing designation, not a year or a custody date. This documents confinement at the roster’s reporting time, without establishing an admission, transfer, release, new conviction or complete duration. Existing independently sourced custody chronology remains separate. Source: https://www.marxists.org/history/usa/pubs/dailyworker/1925/1925-ny/v02b-n297-NYE-dec-29-1925-DW-LOC.pdf#page=5
The February 26, 1924 Daily Worker political-prisoner roster individually prints Henry Matlin with historical prisoner number 35717. The entry appears under San Quentin State Prison, California. This is a contemporary institutional identifier, not a federal BOP register number. No admission or release date, individual sentence length, actual duration, organizational membership or present status is inferred.
