US President, Barack Obama and the Prince of Wales, Prince Charles have paid tribute to the star by referring to his best-known roles.
Obama says about the actor who was found dead in his home on Monday night, ‘He was an airman, a doctor, a genie, a nanny, a president, a professor, a Peter Pan, and everything in between. But he was one of a kind.
‘He arrived in our lives as an alien – but he ended up touching every element of the human spirit.
‘He gave his immeasurable talent freely and generously to those who needed it most – from our troops stationed abroad to the marginalised on our own streets.’
Prince Charles, who met Williams in 2008 for his 60th birthday celebrations, led British tributes.
He said: ‘He was a remarkable man, whose wonderful frenetic humour brought a special kind of laughter into people’s lives.
‘I greatly enjoyed meeting him on several occasions and his irreplaceable contribution to life will be greatly missed by countless people, including myself.’
