Forest Mars, Sr. and Bruce Murrie were the creators of the M&M. The idea was inspired by the Spanish Civil War soldiers who snacked on chocolates with hard candy shells which allowed the treats to travel easier in the heat.
The first M&M’s went into production in Newark, NJ in 1941. Forest Mars was the son of the founder of the Mars Company, and Murrie was the son of a Hershey president. And that’s the rest of the story.
