Ralston, Robert, School
Why it's listed
Built in 1869 at American and Bainbridge Streets in Philadelphia, the Ralston Public School is a rectangular brick schoolhouse designed by Louis Esler, the first Supervisor of Buildings and Repairs hired by the School District's Board of Controllers in 1867. The plan placed four small classrooms on each floor, flanked by enclosed staircases. Esler's design follows the so-called Philadelphia or Sloan Plan, derived from Samuel Sloan's 1852 publication The Model Architect. Although it was built after the Civil War, the building has a distinctly rural character recalling earlier school architecture. It was constructed during a school building boom that followed the depression of the 1850s, when a Department of Buildings was created to meet heavy demand for new schools. Of the 29 schools Esler supervised between 1867 and 1870, the Ralston School is regarded as a rare survivor from his tenure, and it is important as an early example of his work before his designs took on a more individual character.
Significance in brief: The nomination argues the building is an early design by Louis Esler, the first Supervisor of Buildings and Repairs, and that it shows his adoption of the Sloan plan. It is presented as a rare surviving example of the school district's building program after the 1850s depression, and as a remnant of Esler's tenure when 29 schools were designed under his supervision between 1867 and 1870.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
