WILLIAM PENN CHARTER SCHOOL, 8 to 10 South Twelfth Street, was planned in 1684 at a meeting of the Provincial Council, Governor Penn presiding. In 1689, William Penn, writing from England to Thomas Lloyd, President of Council, instructed him to set up a “Public Grammar School in Philadelphia,” the school was incorporated in 1698, and George Keith engaged as head master, 1699. In 1701, William Penn, while on a visit to America, granted the school a charter from his own hand; on the same day he chartered the city itself. This school is the oldest existing chartered school in America; a second and more liberal charter was granted, 1708, and a third charter, under which the school is still conducted, 1711; the originals of all three of these charters are in the school’s possession. The school will be moved to Pinehurst, the Waln estate, twenty-two acres on School Lane near Wissahickon Avenue, Germantown, acquired by gift; field now used for their athletic sports, surface having been adapted for the purpose by the Newhall Engineering Company, Philadelphia, who made there a football oval; an eighteen foot quarter-mile track; and an eighteen foot 220 yard straightway; drainage of these tracks and oval is such, that in eight years, not one scheduled contest has been postponed on account of condition of the ground.
