Margaret Chase Smith (December 14, 1897–May 29, 1995) was a Republican Senator from Maine, and one of the most successful politicians in Maine history. She was the first woman to be elected to both the U.S. House and the Senate, and the first woman from Maine to serve in either. She was also the first woman to have her name placed in nomination for the U.S. Presidency at a major party's convention (1964 Republican Convention, won by Barry Goldwater). She was a moderate Republican and might be termed a Rockefeller Republican. Upon leaving office, Smith was the longest serving female senator in United States history..
