Ten key facts about Robin Williams, drawn from official records and biographical sources.

What was the cause of Robin Williams’ death?

Medical findings: Lewy body dementia

• An autopsy found diffuse Lewy body disease in Williams’s brain, a condition often misdiagnosed as Parkinson’s (ABC News (news outlet)).
• The Lewy Body Dementia Association estimates LBD affects about 1.4 million people in the United States (Lewy Body Dementia Association (nonprofit)).
• The diagnosis was made posthumously; doctors had not seen such extensive disease before (Sky News (news outlet)).

The role of Parkinson’s disease

• Williams had been diagnosed clinically with Parkinson’s disease before his death, but the full extent of the condition was not known until the autopsy (Lewy Body Resource Center (LBD advocacy)).
• The Parkinson’s Foundation notes that his case involved Lewy body dementia, suicide, and Parkinson’s-like symptoms (Parkinson’s Foundation (nonprofit)).

Sobriety at the time of death

• The Marin County coroner reported no evidence of alcohol or illegal drugs in Williams’s system; only therapeutic concentrations of prescribed medications were found (Detroit Free Press (newspaper)).
• He was sober at the time of death, contradicting initial speculation about a relapse.

The implication: Williams’s suicide was not driven by substance abuse but by a severe, undiagnosed brain disease. The Lewy body dementia likely eroded his cognitive and emotional stability.

What did Robin Williams say before he died?

Last words and suicide note

• Williams left a suicide note, but the exact content has not been publicly released (Wikipedia (encyclopedia)).
• According to reports, the note expressed remorse and love for his family, but officials have kept it sealed (CBS News (news outlet)).

Who he called in his final hours

• He reportedly called his wife Marsha before dying, though conflicting accounts suggest he also called his assistant (Yahoo Entertainment (entertainment news)).
• His inner circle described paranoia-filled final days, with Williams fearing he was being investigated for something (Yahoo Entertainment (entertainment news)).

The catch: The exact sequence of his final calls remains unclear, but the paranoia aligns with his undiagnosed dementia.

Why did Disney apologize to Robin Williams?

The dispute over Aladdin’s Genie

• Williams felt Disney used his voice without permission for merchandising after he had a clause in his contract that his voice not be used for toys (Wikipedia (encyclopedia)).
• The controversy strained his relationship with Disney for years.

Disney’s posthumous apology

• In 2015, Disney issued an apology to Williams’s family, saying “We deeply regret that we did not resolve this issue during Robin’s lifetime” (Wikipedia (encyclopedia)).
• The apology helped mend fences, and his family accepted the gesture.

The trade-off: The commercial use of his iconic voice was a point of principle for Williams, but Disney’s late acknowledgment preserved his legacy.

Who inherited Robin Williams’ estate?

His three children and their inheritance

• The estate, valued at approximately $50 million, was mostly left to his children: Zak, Zelda, and Cody (Wikipedia (encyclopedia)).
• His wife Marsha received limited assets due to a prenuptial agreement.

Legal battles over his belongings

• A dispute arose over certain personal items, including memorabilia and watches, but the bulk of the estate was settled without prolonged litigation (Wikipedia (encyclopedia)).

What this means: The children became the primary beneficiaries, ensuring Williams’s wealth supports his family line.

Why did Robin Williams’ wife leave him?

Marsha Garces filed for divorce

• Marsha Garces, his third wife, filed for divorce in 2010, citing irreconcilable differences (Wikipedia (encyclopedia)).
• Williams struggled with depression and addiction during the marriage, which likely contributed to the split.

Reasons cited irreconcilable differences

• The divorce was finalized before his death, and the reasons remain private, though financial and emotional strains were reported (Yahoo Entertainment (entertainment news)).

The pattern: Marital difficulties often accompany severe mental health struggles, and Williams’s case was no exception.
