Robin McLaurin Williams was born July 21, 1951 in Chicago. He briefly studied political science before enrolling at Juilliard School to study theatre. After that, he performed in nightclubs, where he was discovered for the role of Mork on an episode of "Happy Days" (1974), which led to the spin-off, "Mork and Mindy" (1978). Williams is known for wildly improvised stream-of-consciousness comedy in which he will make cultural references and do impersonations and one-liners with rapid switching. For example, most of his dialogue in "Aladdin" (1992) was ad-libbed. Williams received five Grammys for various comedy recordings and one for a recording for children. He also proved to be an effective dramatic actor. He received an Academy Award for Best Supporting Actor in "Good Will Hunting" (1997).
