Tent Chautauquas
Chautauqua was an adult education movement in the United States, highly popular in the late nineteenth and early twentieth centuries. A Chautauqua assembly brought entertainment and culture for the whole community, with speakers, teachers, musicians, entertainers, preachers and specialists of the day.
Tent Chautauquas were traveling versions of the Chautauqua movement, often held in rural locations. The program would be presented, and after several days the Chautauqua would fold its tents and move on.
A notable participant was Eleanor Roosevelt, in Miamisburg, OH, 1940.
