The reports characterize the cause of death differently. EL PAÍS and Deadline described it as natural causes, while The Guardian and SlashFilm attributed it to old age. No exact time of death was provided in the supplied coverage.
According to The Guardian, Zachery McGinnis of Galactic Productions said in a Facebook post that Koenig died at home in North Hollywood surrounded by his daughter and niece. The Guardian identified Galactic Productions as an appearance agency that counted Koenig among its clients.
Koenig joined Star Trek in the 1960s and became the first actor to play Pavel Chekov, the Russian crew member introduced in the television franchise. Deadline described him as originating the role, while SlashFilm and The Guardian identified him as the first actor to portray Chekov.
His association with Chekov continued beyond the original television series. According to SlashFilm and The Guardian, Koenig reprised the role in the first seven Star Trek films derived from the show. Those appearances extended his connection with the character across the franchise’s television and film history.
The available accounts establish the death, its confirmation by Koenig’s representatives, and his connection to the Chekov role. They do not establish an exact numeric date of death in the supplied evidence: EL PAÍS reported that he died on the Sunday before its October 26, 2026 publication, but the specific date is not stated explicitly.
