What The M&M Initials Actually Stand For

by

The initials M&M stand for Mars and Murrie.

The iconic candy was introduced in 1941 by Forrest Mars Sr. (son of Frank C. Mars, founder of Mars, Inc.) and Bruce Murrie (son of William Murrie, long-time president of the Hershey Chocolate Company).

The Story Behind the Partnership

  • Forrest E. Mars Sr.: During the Spanish Civil War in the 1930s, Mars observed soldiers eating chocolate pellets covered in a hard sugar shell to prevent them from melting in warm weather. He secured a U.S. patent for the manufacturing process to recreate the candy commercially.

  • Bruce Murrie: Anticipating wartime chocolate rationing ahead of World War II, Mars brought Bruce Murrie into the business as a 20% partner. This strategic alliance guaranteed that Hershey would supply the necessary chocolate and sugar to manufacture the candies.
