Edward Moore Kennedy (February 22, 1932 – August 25, 2009) was an American politician who served in the United States Senate from Massachusetts for almost 47 years, from 1962 until his death in 2009. A member of the Democratic Party, he was the second most senior member of the Senate when he died and is the fourth-longest-continuously-serving senator in United States history. For many years, Kennedy was the most prominent living member of the Kennedy family. Ted was also the last surviving, longest-living, and youngest son of Joseph P. Kennedy, Sr. and Rose Kennedy. He was the youngest brother of John F. Kennedy—the 35th President of the United States—and Senator Robert F. Kennedy, both victims of assassination, and the father of Congressman Patrick J. Kennedy.
