Thomas David Schall (June 4, 1878 – December 22, 1935) was an American lawyer and politician. He served in both the United States House of Representatives and the United States Senate from Minnesota. He was initially elected and then re-elected as a Progressive but later joined the Republican Party. Schall was elected to the House of Representatives in 1914 and served from March 4, 1915, to March 3, 1925, in the 64th, 65th, 66th, 67th, and 68th congresses. As he was legally blind, he was granted, by House vote, a full-time page to assist him with his work.
