American journalist and longtime syndicated columnist known for straightforward but opinionated political reporting.

After graduating magna cum laude from Harvard University (1932), Alsop was a staff writer for the New York Herald Tribune until 1937, when he began collaborating with Robert Kintner on the column “The Capital Parade” for the North American Newspaper Alliance. He abandoned the column to join the U.S. Navy (1940), and during World War II he served with the American Volunteer Group (Flying Tigers) as an aide to General Claire L. Chennault and was briefly held prisoner by the Japanese in Hong Kong (1942).

Alsop and his brother Stewart (1914–74), both self-styled New Deal liberals and distant cousins of Franklin D. Roosevelt, collaborated (1946–58) on the nationally syndicated column “Matter of Fact,” one of the longest-running columns of its kind, appearing in 300 newspapers thrice weekly. From 1958 to 1974 he was the sole author of the column and adopted a more conservative stance, especially on foreign affairs. Alsop was the coauthor of such books as The 168 Days (1938), Men Around the President (1939), American White Paper: The Story of American Diplomacy and the Second World War (1940), The Reporter's Trade (1958), and FDR, 1882-1945: A Centenary Remembrance (1982).
