Robin Williams’ untimely passing earlier this year on August 11 proved that while the comedian was widely popular and brought laughter and joy to millions worldwide, his personal life was somewhat of a mystery.

That should change in the near future now that Henry Holt plans to publish a high-profile posthumous biography of the comedian’s life.

According to The Hollywood Reporter, the publisher announced Wednesday (August 27) that the book will be the “definitive, comprehensive account of Williams’ life.”

Noted New York Times writer Dave Itzkoff, who wrote the newspaper’s front-page obituary and an extensive profile on the Oscar-winning actor, has been tapped to pen the memoir.

"Robin Williams was a cultural hero of mine,” Itzkoff said in a statement. “In the encounters and interactions I was able to share with him, he was always gentle and generous, humane and thoughtful and hilarious.”

The title and publication date have not yet been set.
