'We spent hours chatting to him, reminiscing about our childhood and our wonderful mother.
He'd been in hospital since Sunday with pnuemonia and had also tested positive for Covid-19.
"When our country and our world was struggling you gave us hope, put a smile on our faces and made us believe that tomorrow would be a good day".
"The a year ago of our father's life was nothing short of remarkable", they said. Our thoughts are with his daughter Hannah and all his family. "He was rejuvenated and experienced things he'd only ever dreamed of", they added.
'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'. Sending love and condolences to family'.
He had initially set out to raise £1,000 in gratitude for the treatment he had received for skin cancer and a broken hip, but ended up attracting donations from 1.5 million supporters.
Captain Tom's initiative, which started in April ahead of his 100th birthday, quickly went viral, resulting in some £33 million (about $40 million) of donations pouring in from both the United Kingdom and overseas.
Today his family confirmed Sir Tom had died, aged 100.
His record-breaking fundraising went towards charity organisation NHS Charities Together, which said the money has helped patients, their families and carers during their most isolated and stressful moments throughout the pandemic.
It was announced earlier this week Capt Sir Tom had contracted the virus after battling pneumonia.
Mr Johnson said on 1 February that he spoke to Captain Tom's family after it was revealed he had been admitted to hospital and called him "an inspiration to everybody in this country during this pandemic".
