Who is Kramer?

Cosmo Kramer (Michael Richards) is the neighbor whose entrances arrive before he does. Schemer, dabbler, co-inventor of the Bro. His first name stayed a secret for six seasons until George pried it out of his mother — even Jerry didn’t know. Based on Kenny Kramer, Larry David’s real-life neighbor, who hadn’t yet signed off when the pilot shot — so in “The Seinfeld Chronicles,” he’s “Kessler.”
