Hugh Hefner, the iconic founder of Playboy magazine, died at his home, the Playboy Mansion, of natural causes at age 91. My father lived an exceptional and impactful life as a media and cultural pioneer and a leading voice behind some of the most significant social and cultural movements of our time in advocating free speech, civil rights and sexual freedom," Cooper Hefner, Playboy Enterprises' chief creative officer and Hugh's son, said in the statement.
