Fans are in mourning this week after actor Richard Herd, who starred in shows like “Seinfeld” and “Star Trek” has passed away after a battle with cancer. He was 87 years-old.

A representative for Herd confirmed his death to The Wrap, saying he passed away this week at his home in Los Angeles, California.

Herd appeared in many televisions and films throughout his decades-long career, but he will likely be best remembered for his recurring role on “Seinfeld” playing Mr. Wilhelm, supervisor to Jason Alexander’s character of George Costanza during his time as an employee of the New York Yankees. Herd appeared in eleven episodes of the classic comedy show, and he once said that it was “easy” to get the part.

“It was fun. It was very inviting,” he said of his audition for the show, according to Daily Mail. “And as I left, I turned around and said, ‘Look, I have to tell you this. I hope it doesn’t make a difference, but I’m a Red Sox fan.’ And they all threw their scripts at me. The next day they said, ‘Come on out and play with us.'”

Herd also made appearances in different shows of the “Star Trek” franchise, appearing in “Star Trek: The Next Generation,” “Star Trek: Voyager,” and “Star Trek: Renegades.”

Herd also found success in movies, appearing in classics like The China Syndrome and All The President’s Men as well as in recent films like Get Out and The Mule. In total, he had 155 credits on his Imdb page, and he appears to have kept working right up to his death.

Even though much of his success was onscreen, Herd never forgot his roots in the theater, which is where he got his start.

“The theatre gave me an identity,” he once said. “It taught me social skills and taught me to listen, and made me more of a maverick.”

Herd is survived by his beloved wife Patricia Crowder Herd, who he was married to for forty years, as well as his son, daughter, and stepdaughter. He is also survived by his legions of fans who will never forget the joy that he brought them for years.
