History. Canadian Marcellus Gilmore Edson (February 7, 1849 â March 6, 1940) of Montreal, Quebec was the first to patent peanut butter, in 1884. Peanut flour already existed. His cooled product had a consistency like that of butter, lard, or ointment according to his patent application.
In popular culture. 1  The artist Vincent Trasov, dressed as Mr. Peanut, ran as a joke candidate in the 1974 Vancouver, British Columbia civic elections. 2  In November 2010, The New Yorker magazine published a spoof confession by Mr. Peanut that he is gay and in a relationship with his new sidekick, Benson. Mr. Peanut appears as a monster in the online game Kingdom of Loathing. References
