Peanut butter was invented and reinvented many times during history.
Peanuts were known as early as 950 B.C. and originated in South America. The ancient Incas used peanuts and were known to have made it into a paste-like substance. As a crop peanuts emigrated from South America to Africa by early explorers and then traveled by trade into Spain who then traded the product to the American colonies. The first commercial peanut crop was grown in Virginia in the early to mid 1840's and in North Carolina beginning around 1818. By 1914, many companies were making peanut butter. Joseph L. Rosenfield invented a churning process that made smooth peanut butter smooth. In 1928, Rosenfield licensed his invention to the Pond Company, the makers of Peter Pan peanut butter. In 1932, Rosenfield began making his own brand of peanut butter called Skippy which included a crunchy style peanut butter.
