Marcellus Gilmore Edson (February 7, 1849 - March 6, 1940) of Montreal, Quebec was the first person to patent peanut butter. Edson, a physician developed the idea of packaging peanut paste for people with bad teeth. Peanut paste was sold for six cents per pound.
He was born in Bedford, Quebec.
He was issued with US patent #306727[1] in 1884.
The patent describes a process of milling roasted peanuts until the peanuts reached "a fluid or semi-fluid state." Edson described the cooled product as having "a consistency like that of butter, lard, or ointment."
