born Jan. 26, 1880, Little Rock, Ark., U.S.
died April 5, 1964, Washington, D.C.
U.S. general.
Son of Gen. Arthur MacArthur (1845–1912), he graduated from West Point, of which he became superintendent (1919–22). He rose through the ranks to become general and army chief of staff (1930–35). In 1932 he commanded the troops that evicted the Bonus Army . In 1937 he took over command of the Philippine military. At the outbreak of World War II he was recalled to active duty; he led the combined Philippine-U.S. forces in the Philippines until it was overrun by the Japanese (1942). From Australia, he commanded U.S. forces in the South Pacific and directed the recapture of strategic islands, returning as promised ("I shall return") to liberate the Philippines in 1944. Promoted to general of the army, he received Japan's surrender on Sept. 2, 1945. As Allied commander of the postwar Korean War in 1950, he stemmed the advance of North Korean troops. His request for authority to bomb China was rejected by Pres. {{link=Truman, Harry S.">Harry Truman ; when MacArthur made the dispute public, Truman relieved him of his command, for insubordination. He returned to the U.S. to a hero's welcome, though many deplored his egotism. He was twice (1948, 1952) seriously considered for the Republican Party nomination for president.
