Raymond Albert "Ray" Kroc (October 5, 1902 – January 14, 1984) was an American businessman. He joined McDonald's in 1954 and built it into the most successful fast food operation in the world. Kroc was included in Time 100: The Most Important People of the Century, and amassed a fortune during his lifetime. He owned the San Diego Padres baseball team from 1974 until his death in 1984. Similar to another fast-food giant, KFC founder Harland Sanders, Kroc's success came late in life when he was past his 50th birthday.

Kroc was born to parents of Czech origin in Oak Park, near Chicago, on October 5, 1902. His father originated from the village Břasy near Plzeň, Bohemia (now the Czech Republic). He grew up and spent most of his life in Oak Park, Illinois. During the First World War he lied about his age and became a Red Cross ambulance driver at 15. During the war, Kroc served in the same regiment as Walt Disney. Between the end of the war and the early 1950s he tried his hand at a number of trades including paper cup salesman, pianist, jazz musician, band member and radio DJ at Oak Park radio station WGES. At one time, Ray worked for room and board at one of Ray Dambaugh's restaurants in the midwest to learn the restaurant business. He eventually became a multi-mixer milkshake machine salesman, traveling across the country.
