The history of peanut butter itself originates in Montreal, Canada, when Marcellus Gilmore Edson patented a peanut paste in 1884 (Krampner, 2012). Following this, in 1895, Dr. John Harvey Kellogg patented a process for creating peanut butter from raw peanuts in search of a healthy food for his patients who had lost their teeth (Nguyen, 2017). It wasn’t until 1922 that peanut butter became increasingly popular due to chemist Joseph Rosefield’s invented process that used partially hydrogenated oil to keep the oil from separating from the butter (Dally, 2012). This is when Heinz really emerged in the peanut butter industry, already having been a successful producer of other common household goods, such as ketchup and pickles (Gale, 2006). In 1923, Heinz became the first major brand of peanut butter to be wholly stabilized by hydrogenation (Krampner, 2012). This piece of ephemera shows us how Heinz attempted to advertise this feature to promote the healthiness and ease of their peanut butter, however, an exact date to when it was published is unknown.
