Daniel Ken Inouye was a United States Senator from Hawaii from 1963 until his death in 2012. A member of the Democratic Party, he was President pro tempore of the United States Senate from 2010 until his death. Until the inauguration of Kamala Harris as vice president in 2021, Inouye was the highest-ranking Asian-American politician in U.S. history. Inouye also chaired various Senate Committees, including those on Intelligence, Indian Affairs, Commerce, and Appropriations.
Inouye fought in World War II as part of the 442nd Infantry Regiment. He lost his right arm to a grenade wound and received several military decorations, including the Medal of Honor. He later earned a J.D. degree from George Washington University Law School. Returning to Hawaii, Inouye was elected to Hawaii's territorial House of Representatives in 1953, and was elected to the territorial Senate in 1957. When Hawaii achieved statehood in 1959, Inouye was elected as its first member of the U.S. House of Representatives. He was first elected to the U.S. Senate in 1962.
Inouye never lost an election in 58 years as an elected official, and he exercised an exceptionally large influence on Hawaii politics.
