Beloved funnyman Robin Williams is dead. The actor and comedian was found unconscious in his home at around noon Pacific time and pronounced dead on the scene. The Marin County Coroner’s office suspects this was a suicide, and his publicist has confirmed Williams was battling severe depression, though he wouldn’t say whether or not Williams killed himself. Williams was 63.

Since his first film in 1977, Williams has had a hand in almost 80 productions, all the while having an active stand-up career. He received critical acclaim for many of his pictures, including multiple best actor nominations for his roles in Good Morning, Vietnam; Dead Poets Society; and Good Will Hunting, though he is best known today for his work in vital childhood movies Aladdin and Flubber and iconic LGBT film The Birdcage.

Williams started the Windfall Foundation with his second wife, a grantmaker organization that works to raise money for charities that request it. In 2010, he donated all proceeds of his Christchurch performance to help rebuild the city, which had been struck by an earthquake. Williams has also performed for U.S. troops stationed in Iraq and Afghanistan, and been a public face for St. Jude Children’s Research Hospital for many years.

Williams had three children with his first two wives, the youngest being 22 now. He leaves behind his third wife, Susan Schneider, whom he married in 2011. Schneider said she was “utterly heartbroken” at her husband’s death.
