Eugene Joseph McCarthy (March 29, 1916 – December 10, 2005) was an American politician, writer, and academic who represented Minnesota in both houses of the United States Congress for over 22 years, first in the U.S. House of Representatives from 1949 to 1959, then in the U.S. Senate from 1959 until his resignation in 1971. A member of the Democratic Party, McCarthy sought the party's presidential nomination in the 1968 presidential election, challenging incumbent President Lyndon B. Johnson on an anti–Vietnam War platform, and ran unsuccessfully for the Democratic nomination for president four more times.
Born in Watkins, Minnesota, McCarthy became an economics professor after earning a graduate degree from the University of Minnesota. He served as a code breaker for the United States Department of War during World War II. McCarthy became a member of the Minnesota Democratic–Farmer–Labor Party (the state affiliate of the Democratic Party) and in 1948 was elected to the House of Representatives, where he served until being elected to the U.S. Senate in 1958.
