US Navy Rear Admiral, World War II Medal of Honor Recipient. He received the award from President Harry S. Truman at the White House on January 20, 1947 for his actions as a lieutenant while a Japanese prisoner of war at Makassar, Celebes, Netherlands East Indies in April 1942. After entering the US Naval Reserve in 1926, he received an appointment to the US Naval Academy at Annapolis, Maryland in 1927 and graduated in June 1931. He performed sea duty on the battleship USS New York, followed by the oiler USS Salinas, the ammunition ship USS Nitro, and the light cruiser USS Trenton. In the spring of 1938, he was assigned to the Asiatic Station and served as executive officer of the minesweeper USS Bittern before joining the destroyer USS Pope in December 1939 as her executive officer, and was serving in that capacity when the US entered World War II in December 1941. He participated in the Naval Battle Balikpapan, the Battle of Badung Strait, and the Battle of the Java Sea, the latter of which resulted in the sinking of his ship and eventual capture by Japanese forces and detainment at a camp in the Netherlands East Indies. It was there that he intervened, at the risk of his own life, in a beating by a guard on a fellow prisoner, which contributed to his Medal of Honor award. He remained a prisoner of war until his release following the Japanese surrender in August 1945. He returned to the US and remained in the Navy, commanding the destroyer USS Turner and the transport USS Montrose during the Korean War. He retired 1 April 1954 and was advanced to the rank of rear admiral. He died at the age of 61. In addition to the Medal of Honor, he received numerous other military awards and decorations, including the Navy Cross, the Bronze Star (with 'V' device), the Purple Heart, and the Prisoner of War Medal. His Medal of Honor citation reads: "For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while interned as a prisoner of war of the enemy Japanese in the city of Makassar, Celebes, Netherlands East Indies, in April 1942. Acting instantly on behalf of a naval officer who was subjected to a vicious clubbing by a frenzied Japanese guard venting his insane wrath upon the helpless prisoner, Comdr. (then Lt.) Antrim boldly intervened, attempting to quiet the guard and finally persuading him to discuss the charges against the officer. With the entire Japanese force assembled and making extraordinary preparations for the threatened beating, and with the tension heightened by 2,700 Allied prisoners rapidly closing in, Comdr. Antrim courageously appealed to the fanatic enemy, risking his own life in a desperate effort to mitigate the punishment. When the other had been beaten unconscious by 15 blows of a hawser and was repeatedly kicked by 3 soldiers to a point beyond which he could not survive, Comdr. Antrim gallantly stepped forward and indicated to the perplexed guards that he would take the remainder of the punishment, throwing the Japanese completely off balance in their amazement and eliciting a roar of acclaim from the suddenly inspired Allied prisoners. By his fearless leadership and valiant concern for the welfare of another, he not only saved the life of a fellow officer and stunned the Japanese into sparing his own life but also brought about a new respect for American officers and men and a great improvement in camp living conditions. His heroic conduct throughout reflects the highest credit upon Comdr. Antrim and the U.S. Naval Service."
