Playboy founder, Hugh Hefner dies at 91

Playboy founder, Hugh Hefner has died at the age of 91. Hugh died peacefully at home Wednesday, surrounded by loved ones.

Hefner's passing comes just over a year after his brother, Keith, died.

Hefner married 3 times -- first to high school sweetheart Mildred Williams in 1949 ... then former Playmate of the Year Kimberly Conrad in 1989 ... and finally Crystal Hefner in 2012. She's 31.

His third marriage came 4 years after breaking up with longtime GF Holly Madison. He's survived by 4 children -- Christine and David from his first marriage and Marston and Cooper from his second marriage.

Hefner founded Playboy in 1953 with Marilyn Monroe gracing the first cover. The magazine landed huge celebrities for years to come -- including Cindy Crawford, Kim Basinger, Pamela Anderson, Madonna, Sharon Stone, Naomi Campbell, Carmen Electra, Drew Barrymore and Kim Kardashian.

The magazine stopped publishing nude photos in 2016 but went back to them in February of this year after Hugh's son, Cooper, was installed as chief creative officer.
