The longest single-person filibuster in the U.S. Senate was from Strom Thurmond who represented South Carolina. His lasted twenty four hours and eighteen minutes. However Thurmond's intentions were not good, as he was one of the most notable racists in 20th century American politics. He was trying to block the Civil Rights Bill of 1957 from being passed. Fortunately he failed and the bill was signed by President Eisenhower.
