William Volker (/ˈvoʊlkər/; German: [ˈfɔlkɐ]; April 1, 1859 – November 4, 1947) was an entrepreneur who turned a picture frame business into a multimillion-dollar empire and who then gave away his fortune to shape much of Kansas City, Missouri, both through the William Volker Fund and anonymously, earning him the nickname of "Mr. Anonymous."[1]
