After clashing with his father—the creator of the Milky Way bar—for a few years at Mars Inc., Forrest Mars Sr. moved to England, where in 1932 he began manufacturing the Mars bar for troops in the United Kingdom. It was during the Spanish Civil War that Mars purportedly encountered soldiers eating small chocolate beads encased in a hard sugar shell as part of their rations. In an age when sales of chocolate typically dropped off during summer months due to the lack of air conditioning, Forrest was thrilled by the prospect of developing a product that would be able to resist melting in high temperatures. He returned to the United States and, shortly thereafter, approached Bruce Murrie, the son of Hershey executive William Murrie, to join him in his new business venture. Anticipating a shortage of chocolate and sugar as World War II raged on in Europe, Mars sought a partnership that would ensure a steady supply of resources to produce his new candy. In return, Murrie was given a 20 percent stake in the M&M product, which was named to represent ‘Mars’ and ‘Murrie.’
