Walter Marvin Koenig (; born September 14, 1936) is an American actor and screenwriter. He began acting professionally in the mid-1960s and quickly rose to prominence for his supporting role as Ensign Pavel Chekov in Star Trek (1967–1969). He went on to reprise this role in all six original-cast Star Trek films, and later voiced President Anton Chekov in Star Trek: Picard (2023). He has also acted in several other series and films including Goodbye, Raggedy Ann (1971), The Questor Tapes (1974), and Babylon 5 (1993). In addition to his acting career, Koenig has made a career in writing as well and is known for working on Land of the Lost (1974), Family (1976), What Really Happened to the Class of '65? (1977) and The Powers of Matthew Star (1982).

Early life
Koenig was born in Chicago, Illinois, the son of businessman Isadore Koenig and his wife Sarah (née Strauss). They moved to the Inwood neighborhood of Manhattan when Walter was a child, where he went to school. Koenig's parents were Russian Jewish immigrants from the Soviet Union; his family had been living in Lithuania when they emigrated, and they shortened their surname from "Königsberg" to "Koenig".
Koenig's father was a communist who was investigated by the FBI during the McCarthy era. Koenig attended Grinnell College in Grinnell, Iowa, with a pre-med major. He transferred to UCLA and received a Bachelor of Arts in psychology. After a professor encouraged Koenig to become an actor, he attended Neighborhood Playhouse School of the Theatre in New York City with fellow students Dabney Coleman, Christopher Lloyd, and James Caan.
Career
Early work
In Gene Roddenberry's first television production, the 1963–64 NBC series The Lieutenant, Koenig played a significant role as noncom Sgt. John Delwyn, who is recommended for Officer Candidates School by the series protagonist, Lt William T. (Tiberius) Rice, played by Gary Lockwood; (in episode 27, "Mother Enemy", aired on April 4, 1964). The plot twist, at the height of the US–Soviet Cold War, is that Sgt Delwyn's visiting mother is a prominent, and politically active, American Communist Party member. This sets up various interesting plot tensions involving Delwyn, Rice, and Rice's CO, Capt. Rambridge, played by Robert Vaughn.
In 1964, Koenig portrayed a New York City juvenile gang leader in an adaptation of Memos from Purgatory for The Alfred Hitchcock Hour.
Star Trek
Koenig began playing Ensign Pavel Chekov, navigator on the USS Enterprise, in the original Star Trek television series in the second season, and continued in the role in all of the films featuring the original cast, including Star Trek Generations.
Koenig was unfamiliar with science fiction before being cast on Star Trek. One of only two actors to audition, he was cast as Chekov almost immediately primarily because of his resemblance to British actor and singer Davy Jones of the Monkees. Show creator Gene Roddenberry hoped that Koenig would increase the show's appeal to young people. The studio's publicity department, however, falsely ascribed the inclusion of Chekov to an article in Pravda that complained about the lack of Russians in Star Trek.
As the 30-year-old's hair was already receding, costume designers fashioned a Davy Jones-style "moptop" hairpiece for him. In later episodes, his own hair grew out enough to accomplish the look with a comb-over.
Roddenberry asked him to "ham up" his Russian accent to add a note of comic relief to the series. Chekov's accent has been criticized as inauthentic, in particular Koenig's substituting the "w" sound in place of a "v" sound (e.g., "wodka" for "vodka" or most famously "wessel" for "vessel"); Koenig has said the accent was inspired by his father, who had the same difficulty with the "v" sound.
Most of Koenig's fan mail came from children, and his popularity with fans contributed to him soon receiving a contract as a regular Star Trek cast member; this surprised Koenig, who had initially been told that Chekov would only be a recurring role. When the early episodes for season two of Star Trek were filmed, George Takei was absent while completing the movie The Green Berets, so Chekov was joined at the Enterprise helm by different characters. When Takei returned, the two actors had to share a dressing room and a single script per episode. This reportedly angered Takei to the point where he considered leaving the show, although Koenig observed in a 2016 interview that, while sharing a dressing room with Takei and James Doohan, the three finally recognised their status as supporting players and after that "didn't think twice about it". Koenig and Takei have since become good friends, to the point that Koenig served as best man at Takei's wedding in 2008.
Later work
Typecast as Chekov, Koenig found a great disparity between the adulation from Trekkies at Star Trek conventions and his obscurity in Hollywood, stating that "people are interested in Chekov, not me". Before the Trek movies started, Koenig found some work as a writer. He submitted freelance scripts to a number of shows, including What Really Happened to the Class of '65?.
After Chekov, Koenig had a recurring role as Psi Cop Alfred Bester on the television series Babylon 5. He was a "Special Guest Star" in twelve episodes and, at the end of the third season, the production company applied for an Emmy nomination on his behalf. He was slated to play Bester on the spin-off series Crusade, but the series was cancelled before his episode was filmed. The character name of "Alfred Bester" was an homage to the science-fiction writer of the same name.
Koenig played "Oro" in two episodes of the Canadian science fiction television series The Starlost, which aired in 1973 on Canada's CTV television network. He filmed a few FMV sequences for a re-released copy of the game Star Trek Starfleet Academy for PCs. The game was later cancelled, but considerable footage from it was recycled for the film Game Over, with Koenig's dialogue dubbed over in order to retrofit his performance into the role of a computer hard drive.
Koenig's film, stage, and TV roles span fifty years. He has played roles ranging from a teenage gang leader (Alfred Hitchcock Presents) to Scandinavian fiancé Gunnar in the Gidget episode entitled "Gidget's Foreign Policy", to a Las Vegas entertainer (I Spy). He returned to space with a starring role in Moontrap and played a futuristic dictator in the video game Maximum Surge.
During the early 1990s, he starred in a touring production of the play The Boys in Autumn, playing a middle aged Tom Sawyer, who reunites with childhood friend Huckleberry Finn. Fellow Trek actor Mark Lenard played Finn.
In addition to acting, he has written several films (I Wish I May, You're Never Alone When You're a Schizophrenic), one-act plays, and a handful of episodes for TV shows: Star Trek: The Animated Series, Land of the Lost, Family and The Powers of Matthew Star.
Humanitarian work
In 2007, Koenig was asked by the human rights group U.S. Campaign for Burma to help in their grassroots campaign about the humanitarian crisis in Burma. As detailed on his official website, he visited refugee camps along the Burma–Thailand border from July 16 to 25, 2007.
Personal life
Koenig married actress Judy Levitt in 1965; she died in 2022. In 1968, they had a son, actor Andrew, who died by suicide in 2010. They also have a daughter, Danielle, a comedienne and writer, who is married to comedian Jimmy Pardo.
In September 2008, Koenig served as best man at the wedding of his Star Trek co-star George Takei to Brad Altman.
Koenig was awarded the Inkpot Award in 1982.
