robin-williams-mrs-doubtfireThe Oscar-winning actor and stand-up comedian Robin Williams, whose range extended from manic mimicry to understated character portrayals, was found dead in his California home on Monday.

In a statement, the local sheriff’s office said that it was treating the death of the 63-year-old star as a suspected suicide.

His wife, Susan Schneider, confirmed the news in a statement released through the actor’s publicist. “This morning I lost my husband and best friend, while the world lost one of its most beloved artists and beautiful human beings. I am utterly heartbroken,” she said.

Williams was last seen alive at the house that he shared with Schneider in Tiburon, north of San Francisco, at about 10pm on Sunday night, the Marin County sheriff’s office said.

President Barack Obama: “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,” Obama said in an official statement Monday evening. “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.
