This politician introduced bills including the "Log Cabin Pre-emption Law" and the Graduation Act, which fixed prices for public land to be sold on a scale from twelve-and-a-half cents to one dollar. In his autobiography, he documented living at the home of Charles Gratiot and his close friendship with fur trader Pierre Chouteau, who financed his career. As an attorney, he feuded with rival lawyer Charles Lucas, and killed him in a duel on Bloody Island. This author of the initial Homestead Act gained the nickname "Old Bullion" for his hatred of paper money. Along with his brother Jesse, he also feuded with William Carroll, which led to a street fight in Nashville where this man was threatened with a horsewhip, and then shot Andrew Jackson in the arm. Later, his daughter eloped with John C. Fremont. For 10 points, name this Missouri senator who shares his full name with the American muralist who was his descendant.
