Margaret Chase Smith

Margaret Madeline Chase Smith (December 14, 1897 – May 29, 1995) was an American politician. A member of the Republican Party, she served as a U.S Representative (1940-1949) and a U.S. Senator (1949-1973) from Maine. She was the first woman to serve in both houses of the United States Congress, and the first woman to represent Maine in either. A moderate Republican, she is perhaps best remembered for her 1950 speech, "Declaration of Conscience," in which she criticized the tactics of McCarthyism.
