Milton S. Hershey

Childless, Hershey and his wife Catherine founded a school for orphan boys in 1909, and in 1918 he transferred most of his fortune, including his controlling stake in the chocolate company, to the Hershey Trust to fund it. The trust still holds a majority of the company's votes for the Milton Hershey School. When the trustees tried to sell the company in 2002, the state attorney general and a public outcry stopped them.
