Korean War Franklin Brooke Nihart (March 16, 1919 – August 30, 2006) was a highly decorated United States Marine Corps colonel.

He was awarded the Navy Cross during the Korean War, and he later wrote the Code of Conduct and oversaw the development of several Marine Corps museums.

Lieutenant Nihart then served as a gunnery officer on board the aircraft carrier USS Saratoga (CV-3), when it unsuccessfully tried to assist Wake Island immediately after Pearl Harbor in December 1941.

Throughout the night of September 15 and into the next morning, Nihart led his battalion in repulsing numerous enemy attacks and was able to maintain a defensive perimeter despite heavy casualties among his Marines.

The NKPA hurricane barrage, according to the Division report, “Reached an intensity that was estimated to surpass that of any barrage yet encountered by the 1st Marine Division in Korea.” The battle was so fierce that a Marine from Nihart's battalion, Corporal Joseph Vittori, single-handedly killed 200 of the enemy with a machine gun before he was killed.

The committee discovered an alarming trend where prisoners of war revealed military secrets to their captors after undergoing brainwashing.

Despite leaving the service again, he continued to fill the position as Deputy Director as a civilian, establishing the Marine Corps Museum at Washington Navy Yard in 1977.
