So it’s fitting that in the wake of the news of Hugh Hefner‘s death, everyone from celebrities to politicians to former Playboy cover models are taking to social media to pay tribute to Hefner and honor his legacy. There were those who admired him and enjoyed time at his infamous Playboy mansion, like former BFFs Kim Kardashian West and Paris Hilton — who spent much of Wednesday night sharing memories of Hefner via text. “RIP to the legendary Hugh Hefner! I’m so honored to have been a part of the Playboy team! You will be greatly missed! Love you Hef!

Hefner, the American icon who in 1953 introduced the world to Playboy magazine and built the company into one of the most recognizable American global brands in history, peacefully passed away today from natural causes at his home, The Playboy Mansion, surrounded by loved ones.” Hefner’s son Cooper, who is also the Chief Creative Officer of Playboy Enterprises, also released a statement. “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. He defined a lifestyle and ethos that lie at the heart of the Playboy brand, one of the most recognizable and enduring in history. He will be greatly missed by many, including his wife Crystal, my sister Christie and my brothers David and Marston, and all of us at Playboy Enterprises,” said Cooper. Hefner quickly rose to fame after the first issue of men’s magazine Playboy published in December 1953, which featured a nude Marilyn Monroe. The same year, Hefner launched media and lifestyle company Playboy Enterprises, Inc., on which he served as a board member until the time of his death. In an August 2017 interview, Hefner’s son Cooper, who took over as chief creative officer of Playboy Enterprises, admitted that it was hard to watch his father get older. “It’s tough to watch him struggle,” he told The Hollywood Reporter of his father getting older. “But I’m just happy it’s physical and not mental. He is survived by his wife Crystal Harris and four children.
