'Star Trek’ Legend Walter Koenig Dead at 90

Published Oct 26, 2026, 12:42 PM EDT A cinematic obsessive with the filmic palate of a starving raccoon, Rob London will watch pretty much anything once. With a mind like a steel trap, he's an endless fount of movie and TV trivia, borne from a misspent youth of watching monster movies on TV, perusing the sun-faded goods at the local video rental shop, and staining his fingers with ink from the Video Movie Guide. Areas of interest include science fiction, film noir, horror flicks, '70s disaster pictures, Bond movies, '90s action, giant robots, dinosaurs, super heroes, and the exuberantly schlocky output of Cannon Films. He also enjoys both Star Trek and Star Wars when they're good, and maybe even more when they're bad. As a Canadian, he also has a vested interest in Canadian movies and TV shows, especially the cheesier ones dubbed "Canuxploitation." An expert on Marvel Comics, he has also written for the Official Handbook of the Marvel Universe, and is a member of the Marvel Research Team. He can frequently be found pontificating on comic-book continuity or bemoaning the misfortunes of the Toronto Maple Leafs on his Twitter account.

Koenig would go on to appear in seven Star Trek movies, and many other science fiction productions. Koenig was 90. Walter Marvin Koenig was born in Chicago on September 14, 1936, and moved to Manhattan as a child; his parents were Russian Jewish immigrants, and changed the family name to Koenig from Königsberg. While studying at UCLA, a professor recommended that he try acting, and subsequently made TV appearances on series like Ben Casey, Alfred Hitchcock Presents, and The Lieutenant. The latter was Gene Roddenberry's first TV production, and he'd later bring Koenig aboard his most famous creation: Star Trek. Brought in to shore up Star Trek's appeal with younger viewers, thanks to his resemblance to Davy Jones of The Monkees, Koenig played Lieutenant Pavel Chekov, a Russian Starfleet officer whose accent Koenig based on his father's. Although he gained a great deal of fame from the series, he found it unsatisfying, and briefly left the show during its third and final season to act in a play. When the show was revived as an animated series, Chekov did not return, but Koenig did come back to pen an episode of the series, "The Infinite Vulcan." Koenig was persuaded to return, along with the rest of the Original Series cast, for the big-screen Star Trek movies; he starred in all six of the films with the original cast, and cameoed in Star Trek: Generations, the film that handed the series over to the Next Generation cast. Koenig died of natural causes; he is survived by his daughter Danielle Koenig, and was predeceased by his son, actor Andrew Koenig, and wife, Judy Koenig.
