Biography
R. V. Taylor was imprisoned at San Quentin State Prison during the era of California's criminal-syndicalism prosecutions, which sent more than a hundred IWW members and labor radicals to San Quentin and Folsom on one-to-fourteen-year terms. He appears on the International Labor Defense's rosters of American class-war prisoners in Labor Defender (1926-27) with inmate number 39350; like most of the rank-and-file labor prisoners of the period, 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 R. V. Taylor, at San Quentin California. Its printed identifier is 39350; 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 Daily Worker political-prisoner Christmas roster of December 17, 1924, lists R. V. Taylor at San Quentin State Prison with historical prisoner number 39350. This establishes a contemporary custody observation, not an admission or release date and not a total duration.
