Clark, Mark Wayne (1896–1984), a United States army officer. He was one of the top military commanders of World War II and the Korean War. In 1942, Clark, then a major general, became General Dwight Eisenhower's deputy for the Allied invasion of North Africa. In October, 1942, he made a secret submarine trip to Algiers, where he secured the cooperation of the Free French forces for the invasion, which took place in November. In 1943, as a lieutenant general, Clark was named commander of the U.S. Fifth Army, which he trained and led in the invasion of Italy. During the Italian campaign, which was the most grueling of the war, Clark was criticized for some of his tactics, including the bombing of the abbey atop Monte Cassino.

In 1944 Clark took command of the Allied 15th Army Group in Italy. He was promoted to four-star general in 1945, and after the war assumed command of American Occupation Forces in Austria, holding that post until 1947. He was commander of the U.S. Sixth Army, 1947–49, and chief of Army Field Forces, 1949–52.

During the Korean War, in April, 1952, Clark succeeded General Matthew B. Ridgway as commander of United Nations forces in the Far East. He signed the Korean armistice in 1953 and retired later that year.

Clark was born at Madison Barracks, New York, the son of an army colonel, and spent his youth at various army posts. He graduated from West Point in 1917, and served as an infantry officer in France during World War I. After his retirement from the army, he was president of the Citadel (The Military College of South Carolina), 1954–66. Calculated Risk (1950) and From the Danube to the Yalu (1954) are memoirs.
