Daniel Tompkins formerly served as Governor of New York. To help fund the state militias for the War of 1812, he loaned his own funds to them. Failing to recover the money through long litigation, his health took a turn and it's believed this induced his alcoholism. He is said to have presided over the US Senate while intoxicated. Tompkins is mentioned by Kris Kringle in the 1947 film "Miracle on 34th Street," but the script places him as VP under John Quincy Adams, when Tompkins actually served under James Monroe.
