Rear Admiral
John Adolph Dahlgren, U.S.N., (
1809-
1870), son of the
Swedish Consul in
Philadelphia,
Pennsylvania, made his career in the
United States Navy. He headed the Union Navy's ordnance department during the
American Civil War and designed several different kinds of guns and cannons that were considered part of the reason the Union won that war. The Naval station in
Dahlgren, Virginia, and Dahlgren Hall at the U.S. Naval Academy in
Annapolis, Maryland, were named for him, and so was
Dahlgren, Illinois.
