Edward “Ted” Kennedy (1932-2009), the youngest brother of President John Kennedy (1917-1963), was a U.S. senator from Massachusetts from 1962 to 2009, making him one of the longest-serving senators in American history. Kennedy entered the Senate after winning a 1962 special election to fill the seat vacated by his brother John when he became president. During his career on Capitol Hill, Ted Kennedy was a spokesman for liberal causes, including civil rights, health care and immigration. A leader of the Democratic Party, he was known for his ability to work with those on both sides of the political aisle. In 1980, Kennedy, whose reputation was tarnished by a 1969 car accident, made a failed bid for the Democratic presidential nomination. Dubbed the “liberal lion of the Senate,” he died of cancer at age 77 and was buried at Arlington National Cemetery.
