Introduction

The mansion house at 3905 Spruce Street now occupied by WXPN has been associated with the University of Pennsylvania since its purchase by transportation baron Joseph D. Potts in 1875. For more than forty years the "Carriage House" at the rear of the property served as a support facility for many of the functions of the International House of Philadelphia, which purchased the Potts mansion in 1917 and continued on that site until 1959. The collections of the University Archives and Records Center at the University of Pennsylvania, augmented by information found in the collections of the Philadelphia City Archives and the Historical Society of Pennsylvania, provide the factual basis for the account which follows below in seven sections.
