>Although often credited with its invention, George Washington Carver did not invent peanut butter.[8] By the time Carver published his document about peanuts, entitled "How to Grow the Peanut and 105 Ways of Preparing it For Human Consumption" in 1916,[9] many methods of preparation of peanut butter had already been developed or patented by various pharmacists, doctors, and food scientists working in the US and Canada.[10][11][12]
