General Joseph Lawton Collins (May 1, 1896 – September 12, 1987) was a senior United States Army officer. During World War II, he served in both the Pacific and European Theaters of Operations, one of a few senior American commanders to do so. He was Chief of Staff of the United States Army during the Korean War. Collins' elder brother, Major General James Lawton Collins, was also in the United States Army. His nephew, Brigadier General James Lawton Collins Jr. served in World War II, the Korean War and the Vietnam War. Another nephew, Michael Collins, was the command module pilot on the Apollo 11 mission in 1969 that put the first two men on the Moon and retired from the United States Air Force as a major general. Early life and military career Collins was born in New Orleans, Louisiana, into a large Irish Catholic family on May 1, 1896. He entered the United States Military Academy at West Point, New York in June 1913, at the age of 17, and graduated on April 20, 1917, exactly two weeks after the American entry into World War I, and shortly before his 21st birthday. Due to the outbreak of war, the graduation was several weeks early. He graduated 35th in his class of 139. Among those he graduated alongside were Matthew Ridgway, Mark W. Clark (who shared the same birthday as Collins and, as the two youngest cadets, were both known as the "class babies"), Bryant Moore, Ernest N. Harmon, William C. McMahon, Norman Cota, Laurence B. Keiser, William W. Eagles, William Kelly Harrison, Jr. and Frederick Augustus Irving. All of these men were, like Collins, destined to become general officers and later to achieve high rank in the army, with Ridgway, along with Collins, becoming Army Chiefs of Staff and Clark becoming a four-star general. Collins was commissioned as a second lieutenant into the Infantry Branch of the United States Army and was assigned as a platoon and later company commander with the 22nd Infantry Regiment. He was promoted to first lieutenant in May 1917, and temporary captain in August. He attended the United States Army Infantry School of Arms at Fort Sill, Oklahoma and served with the regiment at various locations between 1917 and 1919. He was promoted to captain in June 1918, and to temporary major in September, and took command of the 3rd Battalion, 22nd Infantry
