Russell Simmons

Called the "godfather of hip-hop," Russell Simmons has been credited with bringing rap to the mainstream. In the early 1980s, he founded Def Jam Records with Rick Rubin. The label launched legendary hip-hop acts like Run-D.M.C., the Beastie Boys and LL Cool J. Simmons' hip-hop business empire quickly expanded beyond music. At various points, it has included Def Comedy Jam, which introduced comedians Chris Rock and Martin Lawrence, and the Phat Farm clothing line.
