M & M’s are named after Forrest Mars and Bruce Murrie and were produced by Mars, Incorporated in 1941. Forrest Mars got the idea of M & M’s from seeing soldiers during the Spanish Civil War eating pieces of chocolate with a hard covering preventing them from melting. When M & M’s began to sell during World War II, they were sold solely to the military. At first, the “m” on the candies was printed in black, but a few years later it was changed to white. In 1976, the red M & M’s were eliminated because it was said that red dyes contained amaranth, a cancer inducing chemical. Although the red dye that was used on M & M’s did not contain amaranth, it was done to lessen the worries of the public and so the red M & M’s were replaced with orange ones. The red M & M’s were brought back at a later time but the orange M &M’s were kept.
