In May 1937, an event took place that would become a touchpoint and rallying cry in the history of labor organization: the Battle of the Overpass. Numerous United Auto Workers organizers, including Walter Reuther and Richard T. Frankensteen, arrived at the Ford Motor Company Rouge plant in Dearborn, Michigan, shortly before shift change, intending to hand out flyers to plant workers. Instead, the organizers were attacked by Ford employees. We have just digitized a number of photographs documenting those events, including this one showing union representative Robert Sentman being chased by Ford Service Department men. View photos from our digital collections about the Battle of the Overpass, or learn more about the day’s events and aftermath on our website and via the Walter P. Reuther Library.
