Esler, the first Building Supervisor for the Philadelphia school district.","why_significant":"The nomination argues the building is one of the few surviving examples of school architecture from the 1870s. Its exterior design is described as fairly sophisticated for its time, with larger plan and massing and more refined detailing than the earlier Esler schools. It is regarded as very much residential in character despite standing out on the street.","narrative":"Built in 1874-75 in Germantown, Philadelphia, the Germantown Grammar School was designed by Louis H. Esler, who had been appointed the first Building Supervisor for the Philadelphia school district in 1867. The office was created after the 1854 consolidation of the city brought new pupils who needed additional schools, and the post-Civil War years saw a boom in school construction under the position. Earlier school buildings in the city were often commissioned from architects and builders following the Sloan Plan. Esler's design is larger in plan and massing than his earlier work and shows more refined detailing. Its exterior is considered fairly sophisticated for its period. Surrounded by high Victorian residences, the building takes a residential character while still standing out on its street. Its significance rests on its rarity, as one of the few surviving school buildings from the 1870s in Philadelphia, and on the quality of its architecture.","period_of_significance":null,"architect_builder":"Louis H.
