The following is from "The History of Peanut Butter by Mary Bellis.
Agricultural chemist, George Washington Carver discovered three hundred uses for peanuts and hundreds more uses for soybeans, pecans and sweet potatoes. He did start popularizing uses for peanut products including peanut butter, paper, ink, and oils beginning in 1880. (With the most famous of Carver's research taking place after he arrived in Tuskeegee in 1896.) However, Carver did not patent peanut butter as he believed food products were all a gift from god. The 1880 date precedes all the above inventors accept of course for the Incas, who were probably first. It was Carver that made peanuts a significant crop in the American south in the early 1900's.
