Forrest Mars, Sr., son of the Mars Company founder, Frank C. Mars, copied the idea for the candy in the 1930s during the Spanish Civil War when he saw soldiers eating British-made Smarties, chocolate pellets with a colored shell of what confectioners call hard panning (essentially hardened sugar syrup) surrounding the outside, preventing the sweets (candies) from melting. Mars received a patent for his own process on March 3, 1941. Production began in 1941 in a factory located at 285 Badger Avenue in Clinton Hill, Newark, New Jersey. When the company was founded it was M&M Limited. The two 'M's represent the names of Forrest E. Mars Sr., the founder of Newark Company, and Bruce Murrie, son of Hershey Chocolate's president William F. R. Murrie, who had a 20 percent share in the product. The arrangement allowed the candies to be made with Hershey chocolate, as Hershey had control of the rationed chocolate at the time.
