About Joan Kroc
Joan Beverly Kroc, also known as Joni, was an American philanthropist and the third wife of McDonald's CEO Ray Kroc. She later bequeathed an additional $1.6 billion to open Salvation Army Kroc Centers across the nation, the largest one-time gift ever recorded. As the Padres owner, Kroc started Major League Baseball's first employee-assistance program for players and staff with drug problems. In 2002, Kroc Center, a large Salvation Army community center that she helped fund—to the tune of $87 million—opened to the public. Another of her major donations was $225 million to National Public Radio (NPR) including $5 million to her local public radio station, San Diego's KPBS.
