John Cooper, later known as Jackie Cooper, was born in Los Angeles, California, to Mabel Leonard, an Italian-American stage pianist, and John Cooper. Through his mother, he was the nephew of actress Julie Leonard, screenwriter Jack Leonard, and director Norman Taurog.
After serving with the Navy in the South Pacific during World War II, Jackie Cooper quietly compiled one of the most distinguished peacetime military careers of anyone in his profession. In 1961, as his TV series Hennesey was enhancing naval recruiting efforts, he accepted a commission as a line officer in the Naval Reserve, taking on duties in recruitment, training films, and public relations.
With a multi-engine pilot license, Jackie Cooper later co-piloted jet planes for the Navy, earning him the honor of being an Honorary Aviator, authorized to wear wings of gold, a distinction shared by only two others in naval aviation history. By 1976, he had risen to the rank of captain, and was in uniform aboard the carrier USS Constellation for the Bicentennial celebration on July 4.
In 1980, the Navy proposed a period of active duty at the Pentagon, which would have resulted in a promotion to rear admiral, bringing him on par with Air Force Reserve Brigadier General James Stewart. However, Jackie Cooper felt his absence would impact his goal of directing motion pictures, and reluctantly declined the offer.
Throughout his military career, Jackie Cooper received Letters of Commendation from six secretaries of the Navy. He also served as honorary chairman of the U.S. Navy Memorial Foundation and was a charter member of VIVA, an organization dedicated to returning POW-MIAs from Vietnam.
Upon his retirement in 1982, Jackie Cooper was decorated with the Legion of Merit by Navy Secretary John F. Lehman Jr. No performer in his industry has achieved a higher uniformed rank in the U.S. military, except for James Stewart.
