Born on August 1, 1920 at Ridgewood, New Jersey, he grew up there and in Sebring, Florida.
He graduated from the Georgia Institute of Technology in 1941 and enlisted in the Army Air Corps, completing his avition training and received promotion to Captain early in 1942.
After service in the United States and Alaska he was ordered in March 1943 to the 49th Fighter Group of the 5th United States Air Force, then operating in the Southwest Pacific Area and in particular providing an early air screen for Darwin and Northern Australia. Subsequently he was transferred to the 475th Fighter Group, 13th Air Force, where he won promotion to Major.
He was already a leading ace with a record of 31 Japanese planes shot down when he volunteered on December 5, 1944 to lead a squadron of P-38s on a bomber escort mission over Mabalacar Airdrome on Luzon, Philippines. He shot down 3 of 20 Japanese Zero fighters that attacked his squadron. The next day, on a similar mission over Clark Field, near Manila, he exposed himself in order to draw fire away from a crippled bomber and shot down 3 of the 4 fighters that were attacking it. Another score on his way home that day brought his total to 38. On January 7, 1945, while leading a flight of four P-38s over Los Negros Island, he attempted a highly-dangerous maneuver in order to aid a comrade who was losing an encounter with a Japanese Zero and crashed.
He was posthumously awarded the Medal of Honor in March 1946 for his actions on December 25-26, 1944 and January 7, 1945. His score of 38 enemy kills made him the second leading American fighter pilot of World War II, following Major Richard Bong. McGuire Air Force Base in his home state of New Jersey was named in his honor.
