Walter Koenig, star of Star Trek, dies aged 90

The death has been announced of the American actor Walter Koenig, best known for his portrayal of Pavel Chekov in the Star Trek series and films. He was 90.

US entertainment trade publication The Hollywood Reporter says Koenig's representative announced that the actor died on Sunday of natural causes at his home in North Hollywood.

Announcing his client's death, Zachery McGinnis, the founder of Galactic Productions, said: "Today we mourn the passing of Walter Koenig, whose talent, warmth, and unforgettable performances left a lasting mark on generations of fans around the world."

"Walter's legacy extends far beyond the screen," McGinnis continued.

"Through countless convention appearances and interactions with fans, he shared his kindness, wit, and appreciation with everyone fortunate enough to meet him.

"He understood what Star Trek meant to people and embraced the community that grew around it."

Koenig played Ensign Pavel Andreievich Chekov in 36 of the 50 Star Trek episodes that first aired between 1967 and 1969 and in numerous spin-off films, shows, and video games in subsequent decades.

He also starred as Alfred Bester in another sci-fi series, Babylon Five.

His many other screen credits included the series The Virginian, Columbo, and Futurama.

Koenig was also a director, writer, and acting teacher.

He published his memoir, Warped Factors: A Neurotic's Guide to the Universe, in 1998.

Koenig was married to actress Judy Levitt, who died in 2022.

Their son Andrew died in 2010, and he is survived by their daughter Danielle.

Paying tribute, George Takei, who starred alongside Koenig as Star Trek's Hikaru Sulu, said: "My heart is heavy. Walter Koenig, our Ensign Pavel Chekov, passed away early today."

"Walter and I met on the bridge of the Enterprise in the 1960s, and we stayed friends for nearly six decades," Takei continued.

"When Brad (Altman) and I married in 2008, Walter stood beside us as our best man.

"Just last month, on Sept. 14, he turned 90, on the same day Brad and I celebrated our 18th wedding anniversary.

"I will always treasure that he and I shared that date."
