Established on July 4, 1839, Upper Darby School District has a long and distinguished history of providing public education for its residents. The first School Board President was Dr. George Smith. According to A History of Upper Darby (1972), Dr. Smith was a “botanist, an educator, a farmer, a geologist, an historian, a physician, a judge, a scientist, a senator, and a servant of his friends and neighbors.” In 1836, Dr. Smith was Chairman of Pennsylvania’s State Senate Education Committee and drafted the final version of Pennsylvania’s Free Public School Act. The Act, approved on June 13, 1836, overcame years of opposition to the concept of free education for all children, and authorized state funding for local school districts. For more information about Dr. Smith see the Upper Darby Historical Society website.
