The 100-year-old veteran, Captain Sir Tom Moore has died with coronavirus complications.
He was admitted to Bedford Hospital on Sunday.
Sir Tom came into fame after he raised almost £33m for NHS charities by walking laps in his gardens.
Tributes have continued to pour in for the fundraiser after the news of his death hits the public.
The Queen of England sent a personal tribute to his families, “recognising the inspiration he provided for the whole nation and others across the world.”
Speaking of his death, Sir Tom’s daughters said the family shared ‘laughter and tears’ in his final few hours.
Hannah Ingram-Moore and Lucy Teixeira described 2020 of their father’s life as “remarkable”.
The veteran tested positive for COVID-19 last week.
He could not be vaccinated at the time as he was receiving other medication for pneumonia, the family said.
The former military became a celebrity after walking 100 laps of his garden in Marston Moretaine in Bedfordshire in 2020 during the first lockdown.
His walk raised over thirty million for the NHS, and his name became a household name as many described him as “inspirational”
The Queen knighted him in July in a special ceremony at Windsor Castle.
The UK Prime Minister said in a statement that “Captain Sir Tom Moore was a hero in the truest sense of the word. In the dark days of the Second World War he fought for freedom and in the face of this country’s deepest post-war crisis he united us all, he cheered us all up, and he embodied the triumph of the human spirit.
“He became not just a national inspiration but a beacon of hope for the world. Our thoughts are with his daughter Hannah and all his family.”
Mr Johnson has reportedly called Mrs Ingram-Moore to offer his condolences.
The daughters said in a statement that “It is with great sadness that we announce the death of our dear father.
“We are so grateful that we were with him during the last hours of his life; Hannah, Benjie and Georgia by his bedside and Lucy on FaceTime.
“We spent hours chatting to him, reminiscing about our childhood and our wonderful mother. We shared laughter and tears together.
“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.
“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.”
Born on April 30, 1920, in Keighley, West Yorkshire, Sir Tom attended Keighley Grammar School and completed an apprenticeship as a civil engineer before he joined the Army.
He joined the eighth battalion of the Duke of Wellington’s Regiment (8 DWR), a unit that was later converted to operate Churchill tanks as part of the Royal Armoured Corps (RAC).
