Louis Napoleon Stodder was a U.S. Navy officer who served in the American Civil War as acting master on the famous USS Monitor when it fought the Merrimack at Hampton Roads on March 8–9, 1862. He is also noted for his heroic efforts in the final hours before Monitor sank in a violent storm at sea off Cape Hatteras that same year. He later commanded USS Adela and served in the East Gulf Blockading Squadron. After the Civil War, he was promoted to captain and served with distinction, commanding other vessels and served in other capacities. He continued serving in the Navy until 1902. When he retired, Stodder lived out the remainder of his years in New York.

USS Monitor was an ironclad warship built for the United States Navy during the American Civil War and completed in early 1862, the first such ship commissioned by the Navy. Monitor played a central role in the Battle of Hampton Roads on 9 March under the command of Lieutenant John L. Worden, where she fought the casemate ironclad CSS Virginia to a stalemate. The design of the ship was distinguished by its revolving turret, which was designed by American inventor Theodore Timby; it was quickly duplicated and established the monitor class and type of armored warship built for the American Navy over the next several decades.
