Biography
Arthur Springer was a Brooklyn pacifist, one of the first two organizers of the 1958 nonviolent campaign against the Atlas ICBM missile base near Cheyenne, Wyoming. Arrested for trespassing, he pleaded not guilty and used his time on bond to rally support for the protest.
The National Guardian’s September 22, 1958 Cheyenne report states that Arthur Springer of Brooklyn pleaded not guilty following the missile-base protest arrest and was at liberty on $450 bond, organizing support for the campaign. It does not report an acquittal or final trial outcome, nor an exact bail-release day.
