What are the first names of the brothers who founded McDonald's?

The first names of the brothers who founded McDonald’s were Richard and Maurice.

The brothers opened a barbecue restaurant in San Bernardino, California, in 1940. After studying their sales, they realized hamburgers generated most of their revenue, so they redesigned the business around a smaller menu and faster service.

In 1948, Richard and Maurice introduced the Speedee Service System, an early fast-food production model that emphasized standardized preparation, low prices, and quick customer service. They began franchising the concept in 1953, several years before Ray Kroc became involved.

A common mix-up is crediting Ray Kroc as the original founder. Kroc did not establish the brothers’ first restaurant; he became their franchising agent in 1954 and bought their company interests in 1961. The brothers’ full names were Richard James McDonald and Maurice James McDonald, who was often called Mac.
