Playboy Magazine founder Hugh Hefner died last week at the age of 91. He died at his home, the Playboy Mansion, in Holmby Hills, California.

Hefner’s death certificate lists that he went into cardiac arrest and suffered from respiratory failure, according to E! News Wednesday. Hefner was also battling E. coli and a blood infection before his death, and there were listed as contributing factors.

“I am heartbroken. I am still in disbelief,” Hefner’s wife Crystal told People magazine. “He gave me life. He gave me direction. He taught me kindness. I will feel eternally grateful to have been by his side, holding his hand, and telling him how much I love him. He changed my life, he saved my life. He made me feel loved every single day.”

Hefner was laid to rest Saturday at the Westwood Village Memorial Park Cemetery in a crypt next to Marilyn Monroe. Hefner bought the crypt in 1992.

The Playboy Mansion will be renovated by Hefner’s neighbor, Daren Metropoulos, who bought the property last year, with the stipulation that Hefner and his wife could live there until he died. He bought the property for $100 million.

Hefner published the first edition of Playboy Magazine in December of 1953. The magazine featured nude images of Monroe, whom Hefner never met.

Hefner was lauded for promoting civil rights, the first amendment and helping to shepherd in the sexual revolution. He has also been critiqued for ushering in a new kind of objectification for women, and his nasty fights with feminists.

Hefner leaves behind four children, Christie and David whom he had with his first wife Millie Williams, and Marston and Cooper, whom he had with his second wife Kimberly Conrad.

Hefner will be played by actor Jared Leto in an upcoming biopic of his life.
