While many associate George Washington Carver with peanut butter, he did not invent it; he was, however, a pioneer in discovering over 300 uses for peanuts. The first patent for 'peanut paste' was actually granted to Canadian Marcellus Gilmore Edson in 1884. He wanted to create a protein-rich food for people who had difficulty chewing solid food. Later, Dr. John Harvey Kellogg (of cereal fame) patented a process for making peanut butter from steamed peanuts in 1895. The 'everyday' creamy version we know today was perfected by Joseph Rosefield, who in 1922 developed a process for 'hydrogenating' the oil. This prevented the peanut oil from separating and floating to the top, allowing the product to be shelf-stable for months.
