Biography
Robert A. Campbell was a former Ohio Communist Party education director. Federal agents arrested him on October 6, 1953 in the Ohio Smith Act roundup and initially held him under $25,000 bail. After a fourteen-week trial, the jury acquitted Campbell and three codefendants on February 10, 1956. The reviewed record does not establish a custodial interval after his arrest.
National Guardian, October 19, 1953, national page 16: The paper reports the October 6 early-morning FBI roundup of seven Ohio Communist organizers, identifying this defendant as arrested in New York City. Brandt was held under $50,000 bail and the others under $25,000. Campbell is identified as a former Ohio party educational director and Brandt as a former organizational secretary. Bail amounts are conditions set, not proof of payment or release; the report does not establish custody endpoints or actual service totals. The abbreviated Greenfield spelling is retained in source evidence rather than used to replace the fuller existing identity.

Cuyahoga jail custody reported in December 1953
The December 19, 1953 Laisvė, page 3, names Robert Campbell at Cuyahoga County Jail in Cleveland in a current-prisoner greeting roster supplied by a prisoner-aid committee. The individual name and Cleveland case context match this profile. This establishes reported actual jail custody by that contemporary roster, before the later trial and sentencing; it is not merely a sentence or arrest report. The list supplies no initial booking day, release date or complete duration. None is inferred from its publication date or the subsequent sentence.
