When the Allentown State Hospital opened on October 2, 1912, it was the first homeopathic hospital in the state. It was originally called the Pennsylvania Homeopathic Hospital for the Insane. The hospital was built on 209 acres in Hanover Township, which included the former estates of Robert E. Wright and J. Marshall Wright. The site was equal distance between Allentown and Bethlehem, in an area known as Rittersville.
