1970 Environmental Teach-Ins

A decade of growing environmental concern culminated with the first Earth Day in 1970. But prior to being branded as “Earth Day,” the events of April 22, 1970, were organized as a national day of environmental teach-ins at hundreds of universities and colleges across the United States. The Teach-In Committee was formed in 1969 by two U.S. congressmen from opposite sides of the political aisle, Gaylord Nelson and Pete McCloskey. Their outreach to the United Steelworkers of America offers insight into the breadth of the planning underway and involvement sought from national organizations. A printed program from former Penn State professor in psychology, Joachim Wohlwill, details the events at the Clark University teach-in, which included a film viewing, workshops, and remarks from the Governor of Massachusetts.
