Those two letters, it turned out, stood for the surnames of the men themselves—Mars and Murrie—whose combined vision and resources launched a product that would eventually become a worldwide favorite, forever linking their names to one of candy’s most enduring success stories.

The Men Behind the Name

Mars and Murrie brought different strengths to their partnership. Mars had the vision for a new kind of candy, while Murrie, whose father was an executive at Hershey, helped secure the chocolate supplies necessary to bring that vision to life.

The idea itself reportedly traces back to something Mars observed during the Spanish Civil War: soldiers eating chocolates coated in a protective sugar shell. That coating prevented the chocolate from melting, and it sparked an idea that would soon reshape candy production entirely.

From Wartime Innovation to Household Staple

When World War II arrived, M&M’s found an eager audience among American soldiers. The candy’s melt-resistant shell made it ideal for warm conditions and easy to carry, turning it into a practical treat for troops far from home.

Once the war ended, M&M’s didn’t stay confined to military rations. The candy made its way into ordinary households, where its convenience and unique coating continued to win over new fans.

From there, growth came through expansion and reinvention. New varieties, colorful packaging, and memorable advertising campaigns helped push M&M’s beyond domestic shelves and into international markets, cementing its place as a global brand.

A Lasting Legacy

Despite the partnership’s origins, it didn’t last forever. Murrie eventually left the business, but the candy retained the name that honored both founders.

More than eight decades later, millions of people enjoy M&M’s without knowing that its name quietly preserves the story of the two men who created it. What began as a practical wartime solution to a melting problem grew into one of the most recognizable and successful candy brands in history.

The next time someone reaches for a handful of M&M’s, the colorful shells carry more than just sugar and chocolate—they carry a small piece of candy history, one rooted in collaboration, innovation, and a name that has endured far longer than most people realize.
