American comedian Robin McLaurin Williams (born July 21, 1952 in Chicago, IL) began his career as a cocaine-addled improv stand-up comedian, who made a living on tips in the late '70s. Soon after, he achieved national fame as the TV character Mork, an alien who guest-debuted on Happy Days before starring in the successful NBC series Mork & Mindy. Suffering a divorce and achieving sobriety in the late-'80s, his career was even further boosted with a series of sobering late-'80s dramas (Good Morning, Vietnam and Dead Poet's Society) and numerous '90s family films (Aladdin and Mrs. Doubtfire). Ironically, he was voted "Most Likely To Not Succeed" in high school and is now an Oscar-winning actor and comedian, now considered an A-list celebrity who donates to charities on a regular basis. Sadly, on August 9, 2006, Williams entered himself into a rehabilitation center for alcoholism.
