Naval Square, Philadelphia
Naval Square is a gated community within the Graduate Hospital neighborhood of Philadelphia that served as the first United States Naval Academy from 1834 to 1845, when the Naval Academy formed in Annapolis. It continued as a retirement home for sailors and marines and was called the Naval Home until 1976, when the facility was relocated to Mississippi.
William Chauvenet
He was instrumental in the 1845 founding of the United States Naval Academy at Annapolis, Maryland, and taught there for years. He was president of the academic board and in 1851 was part of a board that recommended the course of study be extended to four years. Chauvenet taught in many subjects, including mathematics, surveying, astronomy, and navigation. He helped to establish an astronomical observatory at the naval academy. Chauvenet's contributions were so important that in 1890, Admiral S.R. Franklin proclaimed him "Father of the Naval Academy". A bronze plaque was installed with this inscription in 1916, at the behest of Congress.
