In 1930, breakfast cereal pioneer Will Keith Kellogg donated $66 million in Kellogg Company stock and other investments “to help people help themselves,” launching the W.K. Kellogg Foundation. The foundation began its work in Michigan, but by the 1940s had expanded its work internationally and was breaking ground in areas such as rural children’s health, “mainstreaming” children with disabilities, and the development of the healthcare profession. By its 50th anniversary, the foundation was among the world’s largest private philanthropic organizations.
