Nicholas "Nick" Longworth III was an American politician who became Speaker of the United States House of Representatives. He was a Republican.
A lawyer by training, he was elected to the Ohio Senate, where he initiated the successful Longworth Act of 1902, regulating the issuance of municipal bonds. As congressman for Ohio's 1st congressional district, he soon became a popular social figure of Washington, and married President Theodore Roosevelt's daughter Alice Lee Roosevelt. But their relationship cooled when he opposed her father in the Republican Party split of 1912. Longworth became Majority Leader of the House in 1923, and Speaker from 1925 to 1931. In this post, he exercised powerful leadership, tempered by charm and tact.
