Thomas Hale Boggs Sr. (February 15, 1914–undetermined; presumably October 16, 1972, not declared dead until January 3, 1973), was an American Democratic politician and a member of the U.S. House of Representatives from New Orleans, Louisiana. He was the House majority leader.
In 1972, while he was still Majority Leader, the twin engine airplane in which Boggs was traveling disappeared over a remote section of Alaska. The airplane presumably crashed and was never found. Congressman Nick Begich was also presumed killed in the same accident.
Born in Long Beach in Harrison County on the Mississippi Gulf Coast, Boggs was educated at Tulane University where he received a bachelor's degree in journalism in 1934 and a law degree in 1937. He first practiced law in New Orleans but soon became a leader in the movement to break the power of the political machine of U.S. Senator Huey Pierce Long, Jr., who was assassinated in 1935. Long had previously broken the power of New Orleans politicians in 1929.
