Marcellus Gilmore Edson (February 7, 1849 – March 6, 1940) was a Canadian chemist and pharmacist.

[1][2] Marcellus Gilmore Edson was born at Bedford in Quebec.

In 1884 Edson invented a process to make "peanut paste" for the production of candy, and was awarded United States Patent No.

When cooled, his product had "a consistency like that of butter, lard, or ointment".

The patent describes a process of using heated equipment to mill roasted peanuts until the peanuts reached "a fluid or semi-fluid state", and then optionally mixing the resulting paste with sugar for use in confectionaries.
