Philadelphia Saving Fund Society (PSFS), the nation's first mutual savings bank, was founded in 1816. In 1927 the Society commissioned Howe and Lescaze, a local architectural firm that had previously designed traditional style banks for the institution, to draw up plans for a new building to be constructed at the corner of 12th and Market Streets. This collection is composed of materials from two Philadelphia mutual savings banks which date from the first half of the nineteenth century. The collection has been divided into two series: Philadelphia Saving Fund Society (PSFS) and Western Savings Fund Society (WSFS) which was merged with PSFS in 1982. A significant part of the collection consists of photographs of bank buildings represented by traditional styles and in later years by contemporary suburban sites. The American banking industry has usually conducted business in formal bank buildings. The styles of these buildings have changed with passing fashions of architectural taste. This collection provides a good visual record of these developments.
