Joan Kroc

Joan Beverly Mansfield grew up in West St. Paul, Minnesota, the daughter of a railroad telegraph operator, and trained as a pianist and organist well before her teens. She married Navy veteran Rawland 'Rollie' Smith in 1945; he became a McDonald's franchisee in Rapid City, South Dakota, and the couple had a daughter, Linda, in 1946. Playing organ at the Criterion Restaurant in St. Paul in 1957, she met Ray Kroc, then the driving force behind McDonald's, 26 years her senior and married to someone else, as she was. They reconnected at a company convention twelve years later, divorced their respective spouses within months of each other, and married in 1969.

Ray Kroc built McDonald's into the world's largest restaurant chain; Joan spent the fifteen years of their marriage as his wife and increasingly as his conscience, pushing the company toward what became the Ronald McDonald House concept for families of hospitalized children. When Ray died in 1984, she inherited a fortune estimated above two billion dollars and spent the next nineteen years giving nearly all of it away. The gifts arrived on a scale American philanthropy had rarely seen: 1.5 billion dollars to the Salvation Army in 2003 for community centers nationwide, 200 million dollars to National Public Radio the same year, 50 million dollars each to the University of Notre Dame and the University of San Diego for peace-studies institutes, and tens of millions more for hospice care in San Diego.

The contradiction sat in plain sight: a fortune built on hamburgers and drive-through speed funded some of the era's biggest bets on slowing down and thinking bigger. In 1985 she spent millions on nuclear-disarmament advocacy, reprinting Helen Caldicott's Missile Envy and buying newspaper ads against the arms race, a cause well to the left of the Reagan-era politics surrounding the fast-food industry she had married into. She preferred to give anonymously and often did, but institutions kept insisting on putting her name on things, and she generally let them, ending up on plaques at hospitals, universities and Salvation Army centers across the country. Her giving also moved faster than most foundations' due diligence — nine-figure checks decided in months rather than years, a pace some professional philanthropists considered reckless and Kroc herself apparently considered the point.

Kroc died of brain cancer on October 12, 2003, in Rancho Santa Fe, California, at 75, and her single largest gifts arrived only after she was gone, distributed through her estate exactly as she had planned them. The Salvation Army used its bequest to build more than two dozen Kroc Centers, community and recreation facilities in cities from Baltimore to Phoenix. National Public Radio used its 200 million dollars to build an endowment that still funds its news operation. A nickname followed her past death — 'Saint Joan of the Arches' — that mixed the piety of the giving with the very unpious fortune underneath it.
