Robin Williams

Robin McLaurin Williams (July 21, 1951 – August 11, 2014) was a stand-up comedian and actor who first became famous as the star of Mork & Mindy. That series also helped make his mark as a hailed master of improvisational comedy, whom writers of various productions learned it was often best to accommodate him considering his off-the-cuff humor was often better than their more carefully prepared material.

Williams later became known for his starring roles in the films Good Morning, Vietnam, Dead Poets Society, Mrs. Doubtfire, and Good Will Hunting, for which he won an Academy Award for Best Supporting Actor. He was also well-known for voicing the Genie in Disney's Aladdin and its sequel Aladdin and the King of Thieves.

In 1979, he was announced as a guest star on The Muppet Show in an issue of The Muppet Show Fan Club Newsletter, but did not appear on the series.

Williams appeared on the cover of two issues of Muppet Magazine: Issue 1 (1983) and Issue 14 (1986).

He appeared in several Sesame Street segments:
