The W. K. Kellogg Foundation was founded in June 1930 as the W. K. Kellogg Child Welfare Foundation by breakfast cereal pioneer Will Keith Kellogg. In 1934, Kellogg donated more than $66 million in Kellogg Company stock and other investments to the W. K. Kellogg Trust (equivalent to $1.02 billion in 2020). As with other endowments, the yearly income from this trust funds the foundation.
