"Robin Williams was an airman, a doctor, a genie, a nanny, a president, a professor, a bangarang 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 made us laugh. He made us cry. He gave his immeasurable talent freely and generously to those who needed it most – from our troops stationed abroad to the marginalized on our own streets. The Obama family offers our condolences to Robin’s family, his friends, and everyone who found their voice and their verse thanks to Robin Williams."
Others have shared their condolences with public statements regarding Williams' death:
HBO: "Robin Williams graced HBO for so many years with his uncommon gifts. He never failed to elevate his art and did so with a full, generous and loving heart. Always humble and gracious, Robin was a prince and holds a special place in all our hearts."
Pam Dawber ("Mork & Mindy" co-star): "I am completely and totally devastated. What more can be said?"
John Travolta: "I've never known a sweeter, brighter, more considerate person than Robin. Robin's commitment as an artist to lifting our mood and making us happy is compared to none. He loved us all and we loved him back."
Mira Sorvino: I had the extreme good fortune to get to work with Robin in "The Final Cut." He was an immensely kind, generous man, who went to great lengths to take care of those in his presence. He had a kind of magic to him, lighting up any room he was in, and astounding all with his breathtaking comedic rants which incorporated current events into a kind of dizzying stream of consciousness that had us holding our sides laughing. I treasure the memories I and later my husband shared with him, and am grief stricken that he apparently took his own life. He will always be a light in our hearts. Rest in peace, dear man. Our thoughts and prayers are with his family, we send you love.
Forest Whitaker: "The world has lost a special soul. Robin touched our hearts, he gave us laughter, he gave us joy, he made us think about the impossible. I’m blessed to have been able to walk in his universe. He forever changed this world with his presence. My thoughts and prayers go out to his family and to all those who hold him dear."
Comedian David Steinberg: "Robin Williams and I went on stage together for six months last year playing theaters across the country. Besides seeing his brilliant improvisational mind in action every night was the pleasure in just getting to know him and his generosity and spirit. He looked after Jonathan Winters and put him on his TV shows. He would drive to Santa Barbara weekly to make sure Jonathan was ok. A comic genius looking after another comic genius. Robin looked after everyone. If only he would have looked after himself."
Andy Cohen: Robin was my first celebrity interview when I was starting out at CBS News. I was terrible, interrupting him, a complete novice. And he took total care of me and made sure that I didn’t return to the office a failure. Considering what a huge star he was, he needn’t have shown me so much courtesy. But he did and I never forgot it."
Eric Idle: "I can’t believe my lovely friend is gone. My heart goes out to his wife and his beloved children. He brought us so much joy and laughter."
Minnie Driver: "I never met anyone who loved making people laugh more than Robin. I’d come to watch he and Matt film their beautiful scene on the park bench in 'Good Will Hunting,' and when they broke for lunch we sat around on the grass eating sandwiches; what began as a riff on something or other to make us and the crew laugh suddenly extended to office workers out on their lunch break, enjoying the sunshine, and pretty soon he stood up and his big beautiful voice, full of laughter, reached out to the people who were now hurrying down from the street and across the park to catch his impromptu standup. There must have been 200 hundred people listening and laughing by the time lunch was over. I just remember how broadly he smiled , patted me on the shoulder and said, 'There, now that was GOOD.' I loved him, and I will miss him greatly. My thoughts are with his family and friends."
David Steinberg, manager: "Nobody made the world laugh like Robin Williams. My brother, my friend, my soul mate, I will miss you."
Danny DeVito: "So sad to think about this. Hard to speak. Hard to say. Hard to take. All I can think about is what a joy he was to be with. I’m devastated. I’m sending my love to his family and everyone who loved him. My heart is broken by this news."
Twentieth Century Fox Television: "Robin Williams was a comedy giant, and although we only knew him personally for a season, he was warm, funny and a true professional. His cast and crew both loved him and loved working with him, and our hearts go out to his family and friends. He was one of a kind."
On Twitter, celebrities shared their remembrances and their tributes:
Steve Martin: "I could not be more stunned by the loss of Robin Williams, mensch, great talent, acting partner, genuine soul."
Ellen DeGeneres: "I can’t believe the news about Robin Williams. He gave so much to so many people. I’m heartbroken."
Eddie Izzard: "Robin Williams has died and I am very sad. From every comedian here at the Edinburgh Fringe Festival, we salute him & we say goodbye."
Lindsay Lohan: "Mr. Williams visited me the first day of filming The Parent Trap. I will never forget his kindness. What an enormous loss. My condolences."
Judd Apatow: "When I was 18 I got a job as an intern at Comic Relief just to be near him. A genius and a truly kind man who made the world a better place."
Sesame Street: "We mourn the loss of our friend Robin Williams, who always made us laugh and smile."
