Service Committee until it withdrew from CPS in April 1946.

Philadelphia State Hospital was located in Philadelphia,
Pennsylvania, its patient population about six thousand one
hundred. The American Friends Service Committee opened the unit
in August 1942. The city of Philadelphia had run Byberry as the
Philadelphia Hospital for Mental Diseases. Investigated by
panels and commissions, it was turned over to the Commonwealth
of Pennsylvania and officially named Philadelphia State Hospital
in 1938. World War II created severe staff shortages and
deteriorated conditions for patients. Director: Robert Blanc,
