Walter Koenig, the actor who played Pavel Chekov in the original Star Trek television series and films, has died at the age of 90.
Koenig passed away on Sunday, October 25, in Los Angeles, surrounded by his loved ones, including his daughter and niece, entertainment publication Variety reported.

Variety reported that Koenig, who portrayed the Russian navigator across the original television broadcast and seven Star Trek feature films, died at 90.
His passing marks the loss of one of the foundational figures of the classic USS Enterprise bridge crew, concluding a distinguished career in American entertainment that spanned more than five decades.
Pavel Chekov and Star Trek
Koenig joined the cast of Star Trek at the start of its second season in September 1967, making his debut as Ensign Pavel Chekov. Series creator Gene Roddenberry added the character to appeal to younger audiences, giving Chekov a distinctive haircut inspired by contemporary pop stars.
Positioned at the navigation console alongside William Shatner as Captain James T. Kirk and Leonard Nimoy as Commander Spock, Koenig quickly established Chekov as a vital presence on the Enterprise bridge. The character became famous for his intense loyalty, spirited temperament, and humorous habit of claiming that major cultural and scientific achievements had originated in Russia.
Koenig reprised the role across seven Star Trek feature films, beginning with Star Trek: The Motion Picture in 1979. He continued through Star Trek II: The Wrath of Khan, Star Trek III: The Search for Spock, Star Trek IV: The Voyage Home, Star Trek V: The Final Frontier, Star Trek VI: The Undiscovered Country, and Star Trek Generations in 1994.
Early career and education
Koenig was born on September 14, 1936, in Chicago. Before embarking on a professional acting career, he pursued higher education at the University of California, Los Angeles, where he studied psychology.
Beginning in the 1960s, Koenig began appearing in television series, motion pictures, and theatre productions. Beyond performing in front of the camera, he worked extensively as a screenwriter, director, and author, demonstrating a versatile range across stage and screen.
He remained active in the entertainment industry for more than fifty years, continuing to participate in productions and write until the final years of his life. In 2012, Koenig was honoured with a star on the Hollywood Walk of Fame in recognition of his lifetime contributions to the industry.

Role in Babylon 5
In addition to Star Trek, Koenig earned widespread acclaim for his recurring role in the science fiction television series Babylon 5. He portrayed Alfred Bester, a cold, calculating Psi Cop officer who served as one of the central antagonists of the series.
His performance as Bester earned substantial praise from critics and fans, offering a sharp dramatic contrast to the cheerful optimism of Chekov and demonstrating his range as a dramatic performer.
Family and personal life
Koenig married actor Judy Levitt in 1965, and the pair remained married until her death in 2022. The couple frequently supported each other throughout their respective acting careers.
In 1968, they had a son, actor Andrew Koenig, who died by suicide in 2010. The loss deeply affected Koenig and his family, who spoke openly about mental health following the tragedy.
Koenig is survived by his daughter, Danielle Koenig, a comedian and writer who is married to comedian Jimmy Pardo, as well as his niece.
