Walter Koenig Dies: ‘Star Trek’s Original Ensign Chekov Was 90

Walter Koenig, who originated the role of Ensign Pavel Chekov in the 1960s Star Trek TV series and several subsequent movies about the adventures of the USS Enterprise, has died, according to his rep. He was 90.

Zachery McGinnis of Galactic Productions posted Monday on Facebook that Koenig died of natural causes in North Hollywood but did not provide other details. George Takei, who played Sulu on the original Star Trek, also posted on Koenig’s death.

“Walter’s legacy extends far beyond the screen,” McGinnis wrote in part. “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.” See the full post below.

Koenig played the Russian-American navigator Chekov for second and third seasons of CBS’ Star Trek series from 1967-69 and reprised the role in Star Trek films from 1979-91. The character’s introduction for Season 2 came at the height of the U.S.-USSR Cold War.

The news comes as the original hugely popular and influential Star Trek series created by Gene Roddenberry is marking its 60th anniversary.

“That camaraderie among Star Trek fans became more extensive when they started having conventions,” Koenig said in a2013 interview for the TV Academy Foundation. “It wasn’t only what you’d traditionally call nerds. It was people who had a sense of humanity and a sense of justice. People who had imagination and people who loved monsters. It covered a much larger canvas than was initially thought.”

George Takei paid tribute to Keonig on Monday, writing: “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. When Brad 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.

“Walter was more than Chekov. He was a writer, a teacher, a thoughtful man, and a loyal friend. To the fans who loved him for so many years, thank you. He loved you too.

“Rest well, my dear friend. Keep navigating a steady course.
