General of the Army Douglas MacArthur (January 26, 1880 – April 5, 1964), was an American general and Field Marshal of the Philippine Army. He was a Chief of Staff of the United States Army during the 1930s and later played a prominent role in the Pacific theater of World War II, receiving the Medal of Honor. He was designated to command the invasion of Japan in November 1945, and when that was no longer necessary he officially accepted their surrender on September 2, 1945.
MacArthur oversaw the occupation of Japan from 1945 to 1951 and is credited for implementing far-ranging democratic changes. He led the United Nations Command forces defending South Korea in 1950–1951 against North Korea's invasion.
MacArthur is credited with the military dictum, "In war, there is no substitute for victory." He fought in three major wars (World War I, World War II, Korean War) and was one of the very few men ever to rise to the rank of General of the Army.
