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.
On November 8, 2010, Planters announced that Mr. Peanut would officially be given a voice, supplied by American actor Robert Downey Jr.. In 2011 Mr. Peanut's stunt double named Peanut Butter Doug was introduced to tie in with the Planter's Peanut Butter launch. The character is voiced by Kevin Dillon.
