Michael Richards, American actor and comedian
Michael Anthony Richards (born July 24, 1949) is an American actor, writer, television producer, and retired comedian best known for playing Cosmo Kramer on the television sitcom Seinfeld. He began his career as a stand-up comedian, first entering the national spotlight when he was featured on Billy Crystal's first cable TV special. He went on to become a series regular on ABC's Fridays. He made numerous guest appearances on a variety of television shows, such as Cheers. His film credits include So I Married an Axe Murderer, Airheads, Young Doctors in Love, Problem Child, Coneheads, UHF, and Trial and Error, one of his few starring roles.

From 1989 to 1998, he played Cosmo Kramer on Seinfeld, three times receiving the Primetime Emmy Award for Outstanding Supporting Actor in a Comedy Series. During the run of Seinfeld, he made a guest appearance in Mad About You. After Seinfeld, he starred in his own sitcom, The Michael Richards Show, which was cancelled after 2 months.

When Seinfeld ended in 1998, Richards returned to stand-up comedy. He incited controversy in 2006 after a video was published of him going on a racist tirade against hecklers while performing at the Laugh Factory. The incident severely damaged his career, and due to significant media coverage of the event, he announced his retirement from stand-up in early 2007. In 2009 he appeared as himself in the seventh season of Curb Your Enthusiasm, alongside his fellow cast members for the first time since Seinfeld's finale, as well as lampooning his incident at the Laugh Factory. In 2013, he portrayed Frank in the sitcom Kirstie, which was cancelled after one season.
