It was announced that the 64-year-old British punk fashion pioneer died of mesothelioma, a rare form of cancer, at a hospital in Switzerland.
The Sex Pistols and New York Dolls famed manager and one-time boyfriend and business partner of designer Vivienne Westwood, McClaren once claimed to have invented punk rock.
And while that might be up for debate, he certainly had a large influence over the fashion and music we associate with the rebellious genre.
As the story goes, Westwood and McLaren, then a young band manager, owned a clothing shop in London called Let It Rock, which sold tailored clothing to the so called "teddy boys," then was renamed a few times until it became Sex, a store selling leather bondage gear associated with the S&M lifestyle.
McLaren would outfit members of the Sex Pistols, Bow Wow Wow, Adam and the Ants and Boy George in the hard-edge accessories and other punk rock clothing that he and Westwood would create.
"[People] loved it because it was a new look and it was outlaw," McLaren said of the store and style in a 2007 interview with Vice. "One of our main items were the erotic t-shirts. I used to bring them back from Christopher Street in New York. Some of the kids, by the time they'd walk down the length of Kings Road to Sloane Square, would be arrested. We were raided twice by the police and went to court, but I didn't give a damn. Everything got confiscated but we replaced it and all the kids thought, 'This is the coolest place on earth.'"
McLaren also helped inspire Westwood's signature pirate-themed collections, many of the pieces which were shown at The Metropolitan Museum of Art's Anglo Mania Costume Exhibit in 2006.
