Captain Tom Moore, the British World War II veteran who raised millions of pounds for health service workers on the frontline of the battle against COVID-19, has died aged 100, his family said on Tuesday.

“It is with great sadness that we announce the death of our dear father, Captain Sir Tom Moore,” his daughters said in a statement.

The centenarian caught the public’s imagination in April, when he was filmed doing laps with the help of a walking frame around his garden in the village of Marston Moretaine, north of London.

He hoped to raise 1,000 pounds. Instead, he raised more than 30 million ($41 million) for the National Health Service, broke two Guinness world records, was knighted by Queen Elizabeth, scored a No. 1 single, wrote an autobiography and helped set up a charity.

The Queen will be sending a private message of condolence to the family, according to Buckingham Palace.

Moore was admitted to hospital last week after testing positive for COVID-19.

“The last year of our father’s life was nothing short of remarkable. He was rejuvenated and experienced things he’d only ever dreamed of,” his daughters said.

“Whilst he’d been in so many hearts for just a short time, he was an incredible father and grandfather, and he will stay alive in our hearts forever.”

British prime minister Boris Johnson and David Beckham are among those who have paid tribute to Moore online.
