Biography
Marvin Allen Davidov was born in Detroit on August 26, 1931, moved to St. Paul in 1949 to attend Macalester College and served in the U.S. Army 1953-1955. A 1961 Freedom Rider arrested in Jackson, Mississippi, and a participant in the 1963-1964 Canada-to-Cuba Peace Walk, he founded the Honeywell Project in 1968 after reading a Staughton Lynd article calling on activists to target war-profiteering corporations. He led the Project for over two decades, organizing annual protests at Honeywell's Minneapolis headquarters and shareholder meetings against cluster bombs, missile-guidance systems, anti-personnel mines, and depleted-uranium munitions. Co-authored "You Can't Do That" (2010) with Carol Masters.
Custody-date source review
North Star Legal Foundation v. Honeywell Project, 355 N.W.2d 186 (1984), describes mass trespass arrests on April 18 and October 24, 1983. Davidov is named as a civil respondent, but the opinion does not supply his individual criminal arrest, admission, or release dates. The unsupported October 23 dates are therefore removed rather than replaced with the mass-action date.
St. Louis Park Historical Society's history, based in part on material and an interview provided by Davidov, reports his repeated arrests and three jail sentences across the campaign. Its combined jail total belongs to the group, not Davidov individually. The December 12, 1986 Nuclear Resister, printed page 6, separately reports a recent Davidov conviction with a one-day community-service sentence; that is not evidence of a prison day or of the 1983 case's outcome. Individual custody endpoints remain unknown. His existing identified portrait is retained.
The jointly filed petition individually lists this rider and explicitly states that all petitioners entered pleas of not guilty for their Hinds County Court trials de novo. The previously blank plea field records that county-trial plea only; it does not change the later disposition or establish physical custody dates.
