The first McDonald’s restaurant was started in 1948, by the brothers Maurice and Richard McDonald in San Bernardino, California.

They bought appliances for their small hamburger restaurant from salesman Ray Kroc, who was intrigued by their need for eight malt and shake mixers.

When Kroc visited the brothers to see how a small shop could sell so many milkshakes, he discovered a simple solution. The efficient format that permitted the brothers to produce huge quantity of food at low prices.

Back then, a basic hamburger cost fifteen cents. The reason why the first McDonald’s was so successful was that customers received their food quickly because hamburgers were cooked ahead of time. They were wrapped and heated under heat lamps, since there was no need for waiters and waitresses.
