M&M’s are small colorful button-shaped milk candies with the letter “m” printed in lower case on each candy with vegetable dye. The name M&M is from Forrest Mars, who developed them and Bruce Murrie, his business partner of the time. Forrest Mars invented the recipe for M&Ms chocolate during the Spanish Civil War where is saw soldiers eating pieces of chocolate covered with a hard sugary coating, preventing the candies from melting. Forrest Mars received a patent for his manufacturing process on March 3, 1941. Later Forrest Mars bought Murrie out, gaining complete control over the candy.
