On This Day March 3

On a trip to Spain during the Civil War in the 1930s, Forrest Mars Sr.  son of the founder of the Mars Company Frank C. Mars, encountered soldiers who were eating pellets of chocolate that were encased in a hard sugary coating to prevent them from melting. Inspired by this idea, Mr. Mars went back to his kitchen and came up with the recipe for M&M's. Forrest Mars Sr. received a patent for his manufacturing process of M&M's on March 3, 1941.

Plain/Milk Chocolate M&M's were introduced in 1941. Wikipedia
