When Ray Kroc visited the McDonald brothers in 1954, the restaurant system that would define his career already existed. Richard and Maurice McDonald had reduced their menu, introduced assembly-line production and built an operation around inexpensive hamburgers.
Kroc became their franchising agent. The change took him from selling milkshake machines to expanding the business that used them. His contribution would depend on making the restaurant model repeatable—and on finding a financial structure capable of supporting that expansion.

Best Known For: Expanding McDonald’s through franchising and consistent restaurant operations
Other Activities: Medical-research philanthropy and San Diego Padres ownership
A Working Life Before McDonald’s
Kroc grew up in Oak Park, Illinois. His mother taught piano. He left high school and misrepresented his age to enter Red Cross ambulance-driver training during World War I. The war ended before he was deployed overseas.
Before McDonald’s, his working life included playing piano, selling paper cups and selling Multimixer milkshake machines. He had an established sales career when he visited the brothers’ restaurant.
From the Brothers’ Restaurant to Des Plaines
Richard “Dick” and Maurice “Mac” McDonald opened their restaurant in San Bernardino in 1940. In 1948, they redesigned the operation around a reduced menu and inexpensive hamburgers. Assembly-line production and the elimination of wait staff were central features of their approach.
Kroc’s 1954 visit brought him into that existing business as its franchising agent. On April 15, 1955, he opened his first McDonald’s in Des Plaines, Illinois.
Making the Franchise Model Work
As a franchising agent, Kroc emphasized standard procedures, uniformity and value. Fred Turner joined in 1956 and became an important operations leader. Training became another part of the organization with the opening of Hamburger University in Elk Grove Village in 1961.
But operating standards alone could not finance expansion. Under the early royalty arrangement, franchisees paid 1.9% of gross sales: 0.5% went to the brothers and 1.4% to Kroc’s company. Franchise income was insufficient to fund the growth Kroc sought.
Harry J. Sonneborn helped develop a financial structure to support that growth. Franchise Realty Corporation, formed in 1956, leased restaurant properties and subleased them to operators, supplementing franchise income. Control of the premises also helped the company maintain operating standards. Property ownership became part of the model as well.
Franchisees contributed ideas alongside the common operating procedures. Lou Groen developed the Filet-O-Fish, and Jim Delligatti developed the Big Mac.
The Buyout Changes Kroc’s Role
Kroc and the McDonald brothers disagreed before the 1961 buyout. He purchased their interests for $2.7 million, moving from franchising agent to owner of the name and restaurant system. The acquisition required outside financing, including institutional funds and an insurer.
Members of the McDonald family later alleged in a CBS interview that Kroc had promised a continuing half-percent royalty that went unpaid. Their claim concerns a continuing payment after the buyout, distinct from the earlier royalty arrangement.
McDonald’s went public in 1965. The company expanded beyond the continental United States in 1967, opening restaurants in Canada and Puerto Rico.
Family Life Alongside the Expanding Business
Kroc’s first marriage, to Ethel Fleming, lasted from 1922 to 1961. Their daughter, Marilyn, was born in 1924. He married Jane Dobbins Green in 1963; that marriage ended in 1968. Joan Mansfield Smith became his third wife in 1969.
Joan filed for divorce in 1971. Biographer Lisa Napoli reported that Joan alleged in the divorce papers that Kroc’s temper was violent and ungovernable. The couple reconciled.
A Campaign Contribution Draws Scrutiny
Kroc contributed $250,000 to Richard Nixon’s 1972 reelection campaign.
Critics associated the contribution with federal decisions affecting McDonald’s, including wage and price-control issues. Nixon fundraiser Maurice Stans denied that requests had accompanied the donation.
A Foundation, a Baseball Team and Later Life
Beyond the restaurant business, Kroc founded a medical-research foundation in 1965. Its research fields included diabetes, multiple sclerosis and arthritis. His brother Robert became the foundation’s president in 1969.
Baseball brought a different kind of ownership. In January 1974, Kroc bought the San Diego Padres amid financial instability and threatened relocation to Washington. He committed to keeping the team in San Diego.
Charitable work associated with McDonald’s also depended on collaboration. The first Ronald McDonald House opened in Philadelphia on October 15, 1974, through efforts involving Dr. Audrey Evans, the Hill family, Eagles personnel, McDonald’s regional personnel and community supporters.
Joan developed philanthropic work of her own, including Operation Cork, an alcoholism education initiative.
The Organization Behind Kroc’s Legacy
Kroc became senior chairman in 1977. That year also brought publication of his autobiography, Grinding It Out: The Making of McDonald’s, written with Robert Anderson.
He died in San Diego on January 14, 1984, aged 81.
Kroc’s achievement lay in expanding a restaurant concept through a larger organization. The brothers supplied the original system, Sonneborn helped develop its financial foundation, and operators contributed ideas of their own.
