Robin McLaurin Williams (born July 21, 1951) is an American actor and comedian. Rising to fame with his role as the alien Mork in the TV series Mork and Mindy, and later stand-up comedy work, Williams has performed in many feature films since 1980. He won the Academy Award for Best Supporting Actor for his performance in the 1997 film Good Will Hunting. He has also won two Emmy Awards, four Golden Globes, two Screen Actors Guild Awards and five Grammy Awards.

Most of Williams' acting career has been in film, although he has given some performances on stage as well (notably as Estragon in a production of Waiting for Godot with Steve Martin). His performance in Good Morning, Vietnam (1987) resulted in Williams being nominated for an Academy Award.^[17] Many of his roles have been comedies tinged with pathos.
His role as the Genie in the animated film Aladdin (1992) was instrumental in establishing the importance of star power in voice actor casting. Williams also used his voice talents in Fern Gully, as the holographic Dr. Know in the 2001 film A.I. Artificial Intelligence, in the 2005 animated film Robots, the 2006 Academy Award-winning Happy Feet, and an uncredited vocal performance in the film Everyone's Hero. Furthermore, he was the voice of The Timekeeper, a former attraction at the Walt Disney World Resort about a time-traveling robot who encounters Jules Verne and brings him to the future.

In 1998, he won an Oscar as Best Supporting Actor for his role as a psychologist in Good Will Hunting.Williams has also starred in dramatic films, which earned him two subsequent Academy Award nominations: First for playing an English teacher in Dead Poets Society (1989), and later for playing a troubled homeless man in The Fisher King (1991); that same year, he played an adult Peter Pan in the movie Hook. Other acclaimed dramatic films include Awakenings (1990) and What Dreams May Come (1998). In the 2002 film Insomnia, Williams portrays a writer/killer on the run from a sleep-deprived Los Angeles policeman (played by Al Pacino) in rural Alaska. And also in 2002, in the psychological thriller One Hour Photo, Williams played an emotionally disturbed photo development technician who becomes obsessed with a family for whom he has developed pictures for a long time. In 2006 Williams starred in The Night Listener, a thriller about a radio show host who realizes he has developed a friendship with a child who may or may not exist.
He is known for his improvisational skills and impersonations. His performances frequently involve impromptu humor designed and delivered in rapid-fire succession while on stage. According to the Aladdin DVD commentary, most of his dialogue as the Genie was improvised.
At one point, he was in the running to play the Riddler in Batman Forever until director Tim Burton dropped the project. Earlier, Williams had been a strong contender to play the Joker in Batman. He had expressed interest in assuming the role in The Dark Knight, the sequel to 2005's Batman Begins, although the part of the Joker was played by Heath Ledger, who went on to win, posthumously, the Academy Award for Best Supporting Actor.
He was portrayed by Chris Diamantopoulos in the made-for-TV biopic Behind the Camera: The Unauthorized Story of Mork & Mindy (2005), documenting the actor's arrival in Hollywood as a struggling comedian.
In theatre, Williams has headed his own one-man show, Robin Williams: Live on Broadway, that played at The Broadway Theatre in July 2002.^[28] He made his Broadway acting debut in Rajiv Joseph's Bengal Tiger at the Baghdad Zoo, which opened on Broadway at the Richard Rodgers Theatre on March 31, 2011. He previously appeared opposite Steve Martin at Lincoln Center in an Off-Broadway production of Waiting for Godot.

Robin Williams' first marriage was to Valerie Velardi on June 4, 1978, with whom he has one child, Zachary Pym (Zak) (born April 11, 1983). During Williams' first marriage, he was involved in an extramarital relationship with Michelle Tish Carter, a cocktail waitress whom he met in 1984. She sued him in 1986, claiming that he did not tell her he was infected with the herpes simplex virus before he embarked on a sexual relationship with her in the mid-1980s, during which, she said, he transmitted the virus to her. The case was settled out of court. Williams and Velardi divorced in 1988.
On April 30, 1989, he married Marsha Garces, his son's nanny who was already several months pregnant with his child. They have two children, Zelda Rae (born July 31, 1989) and Cody Alan (born November 25, 1991). However, in March 2008, Garces filed for divorce from Williams, citing irreconcilable differences.
On August 20, 2007, Williams' elder brother, Robert Todd Williams, died of complications from heart surgery performed a month earlier.
Williams is a member of the Episcopal Church. He has described his denomination in a comedy routine as "Catholic Lite – same rituals, half the guilt."
While studying at Juilliard, Williams befriended Christopher Reeve. They had several classes together in which they were the only students, and they remained good friends for the rest of Reeve's life. Williams visited Reeve after the horse riding accident that rendered him a quadriplegic, and cheered him up by pretending to be an eccentric Russian doctor (similar to his role in Nine Months). Williams claimed that he was there to perform a colonoscopy. Reeve stated that he laughed for the first time since the accident and knew that life was going to be okay.
During the late 1970s and early 1980s, Williams had an addiction to cocaine; he has stated that he has since quit. Williams was a close friend of and frequent partier alongside John Belushi. He says the death of his friend and the birth of his son prompted him to quit drugs: "Was it a wake-up call? Oh yeah, on a huge level. The grand jury helped too."
On August 9, 2006, Williams checked himself in to a substance-abuse rehabilitation center (located in Newberg, Oregon), later admitting that he was an alcoholic. His publicist delivered the announcement:

After 20 years of sobriety, Robin Williams found himself drinking again and has decided to take proactive measures to deal with this for his own well-being and the well-being of his family. He asks that you respect him and his family's privacy during this time. He looks forward to returning to work this fall to support his upcoming film releases.

Williams was hospitalized in March 2009 due to heart problems. He postponed his one-man tour in order to undergo surgery to replace his aortic valve. The surgery was successfully completed on March 13, 2009, at the Cleveland Clinic.
Williams is an avid enthusiast of games, even naming both his children after game characters. He named his daughter after Princess Zelda from The Legend of Zelda action-adventure game series. They both have even been featured in an advert for the Nintendo 3DS remake of The Legend of Zelda: Ocarina of Time.On this note, his son may have been named after Cody from the beat 'em up game Final Fight.He also enjoys pen-and-paper role-playing games and online video games, recently playing Warcraft 3, Day of Defeat, Half-Life, and the first-person shooter Battlefield 2 as a sniper.

In the 2006 E3, on the invitation of Will Wright, he demonstrated the creature editor of Spore while simultaneously commenting on the creature's look: "This will actually make a platypus look good." He also complimented the game's versatility, comparing it to Populous and Black & White. Later that year, he was one of several celebrities to participate in the Worldwide Dungeons & Dragons Game Day.

Williams and his former wife, Marsha, founded the Windfall Foundation, a philanthropic organization to raise money for many different charities. Williams devotes much of his energy to charity work, including the Comic Relief fundraising efforts (the program is hosted by himself, Billy Crystal, and Whoopi Goldberg). In December 1999, he sang in French on the BBC-inspired music video of international celebrities doing a cover of the Rolling Stones' "It's Only Rock & Roll" for the charity Children's Promise.
In response to the 2010 Canterbury Earthquake, Williams donated all proceeds of his "Weapons of Self Destruction" Christchurch performance to helping rebuild the New Zealand city. Half the proceeds were donated to the Red Cross and half to the mayoral building fund with the words "I hope this donation will go some way to helping the extensive rebuilding effort in the city."^. Williams has performed with the USO for U.S. troops stationed in Iraq and Afghanistan.
