This fall, the movie The Founder, starring Michael Keaton, will focus the spotlight on Ray Kroc, the man who amassed a fortune as the chairman of McDonalds. But what about his wife, Joan, the woman who became famous for giving away his fortune? Lisa Napoli tells the fascinating story behind the historic couple.Ray & Joan is a quintessentially American tale of corporate intrigue and private passion: a struggling Mad Men–era salesman with a vision fora fast-food franchise that would become one of the world’s most enduring brands, and a beautiful woman willing to risk her marriage and her reputation to promote controversial causes that touched her deeply.Ray Kroc was peddling franchises around the country for a fledgling hamburger stand in the 1950s—McDonald’s, it was called—when he entered a St. Paul supper club and encountered a beautiful young piano player who would change his life forever. The attraction between Ray and Joan was instantaneous and instantly problematic. Yet even the fact that both were married to other people couldn’t derail their roller coaster of a romance.To the outside world, Ray and Joan were happy, enormously rich, and giving. But privately, Joan was growing troubled over Ray’s temper and dark secret, something she was reluctant to publicly reveal. Those close to them compared their relationship to that of Elizabeth Taylor and Richard Burton. And yet, this volatility paved the way for Joan’s transformation into one of the greatest philanthropists of our time. A force in the peace movement, she produced activist films, books, and music and ultimately gave away billions of dollars, including landmark gifts to the Salvation Army and NPR.Together, the two stories form a compelling portrait of the twentieth century: a story of big business, big love, and big giving.
