Pat Cooper, the veteran stand-up comedian whose decades-long career included appearances in Seinfeld and the Howard SternShow, has died. He was 93.

His former personal assistant Steve Garrin confirmed to EW that Cooper died Tuesday in his Las Vegas home. Cooper's wife Emily Conner says the comedian was "telling jokes up until the end," per Garrin. A cause of death has not been reported but Garrin added that Cooper had "a lot of health problems" and, in the last few weeks, knew the end was near.
