Nightclub owner Peter Stringfellow has died at the age of 77, a spokesman has said.
The businessman, who had cancer which he had kept private, died in the early hours of Thursday morning.
The so-called King of Clubs opened many venues around the world and his eponymous club in London's West End became a magnet for celebrities.
The Beatles, The Kinks and Jimi Hendrix were among those he booked in his six decades in the industry.
His family have asked for privacy. He leaves behind his wife, Bella, and four children.
His publicist, Matt Glass said: "It's very sad news. He passed away in the early hours of this morning. It was kept very private, he didn't want to tell. He wanted to keep it a secret."
He added that the Stringfellows club in Covent Garden will continue to operate "as normal".
