Frank Williams, the founder of one of Formula One's most successful and popular teams, has died at the age of 79.
Williams founded the Williams F1 team in 1977 quickly turned the privateer outfit into one of the sport's best, competing and winning against some of the biggest manufacturers in motor racing. The team won nine constructors' championships and seven drivers' championships between 1980 and 1997 and has remained on the grid for over 40 years.
Williams is one of the most important and respected figures in F1 history.
"Sir Frank Williams was one of the kindest people I had the pleasure of meeting in this sport," Sir Lewis Hamilton wrote on Twitter.
"What he achieved is something truly special. Until his last days I know he remained a racer and a fighter at heart. His legacy will live on forever."
In one of sport's great underdog stories, his team started operating out of an old carpet warehouse but quickly became the team to beat in F1. Clay Regazzoni won Williams' first race at the 1979 British Grand Prix, with Alan Jones taking the team's first world championship in 1980.
Williams continued to run his team despite a serious car crash in 1986 that left him with tetraplegia. Remarkably, his team won the constructors' championship that same season, and would win both titles in 1987. Williams then established his team as the dominant force of the 1990s.
He was knighted by Queen Elizabeth II in 1999 for his services to motorsport.
Although he gave up day-to-day running of his team to daughter Claire in 2013, Frank remained team principal until September 2020. Ahead of last year's Italian Grand Prix, the Williams family stood down from the leadership of the team following its sale to private investment firm Dorilton Capital.
Until then, Williams had been the longest-serving and most successful team principal in F1's history.
On Sunday, the Williams team confirmed the news in a statement.
It read: "It is with great sadness that on behalf of the Williams family, the team can confirm the death of Sir Frank Williams CBE, Founder and Former Team Principal of Williams Racing, at the age of 79.
"After being admitted into hospital on Friday, Sir Frank passed away peacefully this morning surrounded by his family. Today we pay tribute to our much loved and inspirational figurehead. Frank will be sorely missed. We request that all friends and colleagues respect the Williams family's wishes for privacy at this time.
"For those wishing to pay tribute, we ask that donations are made in place of gifts to the Spinal Injuries Association, alternatively we would welcome flowers to be placed at the entrance of the team's headquarters in Grove, Oxfordshire. Details of the memorial service will follow in due course."
F1 CEO Stefano Domenicali released a statement saying that Williams "was a true giant of our sport that overcame the most difficult of challenges in life and battled every day to win on and off the track. We have lost a much loved and respected member of the F1 family, and he will be hugely missed. His incredible achievements and personality will be ... etched on our sport forever. My thoughts are with all the Williams family and their friends at this sad time."
Tributes flooded in from the world of motor racing after the news was confirmed.
