Penn State University was founded in 1855. Then known as the Farmers' High School of Pennsylvania, the 400-acre campus had only one main building.With almost 100,000 current students (including students at the Commonwealth Campuses) and having the largest dues-paying alumni association in the world, Penn State continues to be a world leader in education. Since its founding, picture postcards have been published to showcase the buildings and highlight the student activities while documenting the school's narrative.
