M&M’s are one of the most recognizable candies in the world. Their colorful candy shells, chocolate centers, and familiar slogan have made them a favorite for generations. Whether you reach for a handful during a movie, sprinkle them over cookies, or enjoy them straight from the bag, you have probably noticed the two simple letters printed on each candy.
But have you ever stopped to wonder what the “M&M” in M&M’s actually stands for?
The answer goes all the way back to 1941, when two men with the same initial teamed up to create a chocolate treat designed to be easy to carry, share, and enjoy. Their partnership brought together two influential American candy-making families and helped launch a product that would eventually become a worldwide favorite.
It's a surprisingly interesting story involving business connections, a clever candy-making idea, and a partnership that gave one of the world's most famous sweets its name. And once you discover what those two letters mean, you may never look at a bag of M&M’s quite the same way again!
What Does M&M Stand For?
The initials M&M stand for Mars and Murrie, the surnames of the two men associated with creating the original candy.
Their full names were:
Forrest Mars Sr.: The son of Frank C. Mars, founder of the company that became Mars, Incorporated.
Bruce Murrie: The son of William Murrie, a prominent executive at the Hershey Chocolate Company.
The partnership brought together two families with important connections to the American confectionery industry.
Forrest Mars brought the business ambition and product concept, while Bruce Murrie's connection to Hershey was valuable because chocolate production was central to getting the new candy off the ground.
The name was a straightforward combination of their surnames:
Mars + Murrie = M&M’s.
It's a simple explanation behind a name that has become instantly recognizable around the world.
Who Were Forrest Mars and Bruce Murrie?
To understand the story behind M&M’s, it helps to know a little about the two men whose names became part of candy history.
Forrest Mars Sr.
Forrest Mars Sr. was an American businessman and the son of Frank C. Mars, who established the business that eventually became Mars, Incorporated.
He spent time developing his experience in the confectionery industry and became interested in creating products that could reach a wide audience. One of the ideas associated with him was a small chocolate candy surrounded by a hard sugar coating.
The concept was clever because ordinary chocolate can become soft and messy when exposed to warmth. A protective outer shell could make chocolate easier to carry and handle.
Forrest recognized the commercial potential of this idea and helped turn it into a product that could be manufactured and sold on a large scale.
Bruce Murrie
Bruce Murrie was the son of William Murrie, a senior executive at the Hershey Chocolate Company.
His family connection was especially important because Hershey was already a major name in American chocolate production. During the early years of M&M’s, the partnership helped provide access to the chocolate needed to manufacture the candies.
Although Forrest Mars and Bruce Murrie came from different candy-industry families, their collaboration brought together useful business relationships and resources.
Their partnership would give the new candy its memorable name.
