Raymond Albert Kroc (October 5, 1902 – January 14, 1984) was an American businessman who was instrumental in turning McDonald's into the most successful global fast food corporation by revenue. He purchased it from the McDonald Brothers in 1961, after several years as their franchising agent, and served as the leader of the company until his death.
Kroc was born in Oak Park, Illinois, and worked a variety of jobs, including as a paper cup salesman and a musician, before eventually becoming a milkshake mixer salesman. In 1954, he visited a hamburger restaurant in San Bernardino, California, owned by Richard and Maurice McDonald. Kroc was impressed with the efficiency and speed of the restaurant's operations, and he convinced the brothers to allow him to franchise the concept.
Under Kroc's leadership, McDonald's grew rapidly due to Kroc's focus on aggressive expansion, opening new restaurants across the United States and eventually internationally.
