Wikipedia: The Westworld Actor Richard Roat Began His Career In 60s
Early in the 1960s, he began his acting career, and since then, he has appeared in several shows like Dynasty, Matlock, Hill Street Blues, Baywatch, Generation, and The Fresh Prince of Bel-Air.
Plus, he made appearances in various 1990s television programs in the final years of his career, including Days of our Lives, 3rd Rock From the Sun, The New Adventures of Superman, Golden Girls, 7th Heaven, Cold Case, and 24.
The part he played on Seinfeld, though, maybe what people will remember him for most.
Elaine Benes, a character portrayed by Julia Louis-Dreyfus, was referred to as a "difficult patient" by the doctor he played in the sitcom's eighth season in which he guest-starred.
In contrast, he will also be remembered for his roles in the television series Cheers, where he played Norm's boss, Mr. Hecht, and Friends, where he played the worried coworker who exposed Ross to dating Elizabeth, a college student.
