Alf Landon, American lieutenant, banker, and politician, 26th Governor of Kansas (d. 1987)
Alfred Mossman Landon (September 9, 1887 – October 12, 1987) was an American oilman and politician who served as the 26th Governor of Kansas, a position he held from 1933 to 1937. A member of the Republican Party, he was the party's nominee in the 1936 presidential election, and was defeated in a landslide by incumbent President Franklin D. Roosevelt.

Born in West Middlesex, Pennsylvania, Landon spent most of his childhood in Marietta, Ohio, before moving to Kansas. After graduating from the University of Kansas, he became an independent oil producer in Lawrence, Kansas. His business made him a millionaire, and he became a leader of the liberal Republicans in Kansas. Landon won election as Governor of Kansas in 1932 and sought to reduce taxes and balance the budget in the midst of the Great Depression. He supported many components of the New Deal but criticized some aspects that he found inefficient.

The 1936 Republican National Convention selected Landon as the Republican Party's presidential nominee. He proved to be an ineffective campaigner and carried just two states in the election. After the election, he left office as governor and never sought public office again. Later in life, he supported the Marshall Plan and President Lyndon B. Johnson's Great Society programs. He gave the first in a series of lectures, now known as the Landon Lecture Series, at Kansas State University. Landon lived to the age of 100 and died in Topeka, Kansas, in 1987. His daughter, Nancy Kassebaum, represented Kansas in the United States Senate from 1978 to 1997.
