How did George Washington Carver discover peanut butter

George Washington Carver discovered three hundred uses for peanuts and hundreds more uses for soybeans, pecans and sweet potatoes. He start popularizing uses for peanut products including peanut butter, paper, ink, and oils beginning in 1880. The most famous of Carver's research took place after he arrived in Tuskeegee in 1896. However, Carver did not patent peanut butter as he believed food products were all gifts from God. The 1880 date precedes all the above inventors except of course for the Incas, who were first. It was Carver who made peanuts a significant crop in the American South in the early 1900's.
