Rear Admiral French Ensor Chadwick USN (February 29, 1844 – January 27, 1919) was a United States Navy officer who became prominent in the naval reform movement of the post-Civil War era.

[3] Following a brief assignment to the newly established Naval Torpedo Station in Newport, Rhode Island, during 1870, Chadwick served in the screw sloop of war USS Guerriere with the European Squadron until 1872.

On leaving the academy in 1875, he reported to the sidewheel steam frigate USS Powhatan as the ship's executive officer.

During this period, he married Cornelia Jones Miller, the daughter of a U.S. Consular official in 1878 and carried out a study on how sailors were trained in Britain, France, and Germany.
