"William Henry Egle was a physician, author and historian who served as the State Librarian of the Commonwealth of Pennsylvania from 1887 to 1889. His body of work documented Pennsylvania's history from its founding through the late 19th century - excerpts of which continued to be reprinted in newspapers following his death in 1901 and are still cited as references by present-day historians and professional genealogists."
