The Life and Career of Gene L. Coon

There’s a particular pleasure in watching Kirk, Spock and McCoy together. The captain is trying to make a decision, Spock is explaining why everyone else is being illogical, and McCoy is reaching the end of his patience. Underneath the arguments, you know these people care about one another. You would happily spend another hour aboard their ship.

Gene L. Coon helped make that feeling part of Star Trek. As a writer and producer on the original series, he strengthened its characters, encouraged its humour and contributed some of its most memorable moral dilemmas. His name deserves a place in any conversation about why this extraordinary little television series stayed with us.

Born Eugene Lee Coon in Beatrice, Nebraska, on 7 January 1924, he showed an early interest in performing, singing on local radio as a child. His route to Hollywood included military service: he enlisted in the United States Marine Corps in 1942 and later returned to active duty during the Korean War, working as a radio correspondent. Long before he wrote about starship captains, he had experienced military life himself.

By the 1950s, Coon was building a television writing career, with credits on programmes including Dragnet, Wagon Train, Maverick and Bonanza. He also wrote novels, including Meanwhile Back at the Front and The Short End of the Stick. These were the working years of a versatile professional who could move between action, character drama and humour.

His screenplay for Don Siegel’s The Killers, released in 1964 and starring Lee Marvin, Angie Dickinson and John Cassavetes, is a particularly good reminder of his range. There was considerably more to Coon’s career than the Enterprise, however much we associate him with it now.

Coon joined Star Trek in 1966, taking over as producer during its first season. Alongside his own scripts, the job involved developing other writers’ material and helping it work within the series. The surviving paperwork reveals how substantial that contribution could be: his notes on Robert Bloch’s first draft of “Wolf in the Fold” ran to sixteen pages.

That is work an audience rarely sees. We remember the finished episode, the guest star or the final line. Coon’s influence reached into episodes that never carried his name as their writer.

D.C. Fontana later credited him with helping McCoy become a lead character and developing the doctor’s affectionate friction with Spock. McCoy gave Kirk someone who would challenge him on human grounds, while Spock could challenge his reasoning. Their disagreements made command feel personal.

For me, the clearest expression of Coon’s approach is “The Devil in the Dark”. It begins with miners being killed by an apparently monstrous creature. The setting promises a hunt through dark tunnels, with something horrible waiting around the corner. Then the story makes us reconsider everything we have been watching.

The Horta is an intelligent being protecting its young, whose eggs the miners have been destroying. Once Spock communicates with it, the problem changes. Kirk has to find a way for both sides to survive. Coon gives the supposed monster a point of view, and suddenly killing it becomes a dreadful answer to the wrong question.

The same episode makes room for McCoy’s glorious protest: “I’m a doctor, not a bricklayer!” That combination is a large part of its charm. There is fear, compassion, a strange new form of life and a doctor grumbling his way towards helping it. The message lands because the characters remain themselves.

“Arena” offers another version of that moral challenge. Coon wrote the teleplay, with Fredric Brown receiving the underlying story credit. Kirk’s fight with the Gorn is one of the most recognisable images in television science fiction, but the ending deserves just as much attention. Having gained the upper hand, Kirk refuses to kill his opponent.

That decision matters more than the homemade weapon or the fight choreography. Kirk has begun to consider the possibility that the Gorn saw the humans as invaders. He can still recognise the horror of the attack on Cestus III while questioning his own desire for revenge. It is a demanding kind of heroism, and a very good reason to keep watching this captain.

Coon’s “Errand of Mercy” introduced the Klingons, giving Star Trek an adversary it would return to across generations. Yet their first appearance is wonderfully awkward for anyone expecting a straightforward victory for the Federation. Kirk and the Klingon commander, Kor, are both ready for conflict. The Organians intervene and stop them.

Our hero has to accept that the people he intended to protect understand the situation better than he does. I love that Coon was willing to leave Kirk looking uncomfortable. The Federation’s good intentions do not automatically make every decision right. That willingness to examine its own heroes would become one of Trek’s great strengths.

His contributions also helped establish characters whose importance grew far beyond their first appearances. He worked on “Space Seed”, which introduced Khan Noonien Singh, alongside Carey Wilber’s originating story and Gene Roddenberry’s revisions. Khan’s creation was a collaborative process, and Coon had a significant hand in the episode that made The Wrath of Khan possible.

He also wrote “Metamorphosis”, introducing Zefram Cochrane. Think of how much later Trek would build around that name. A character first encountered in an intimate story about loneliness and an alien companion eventually became central to humanity’s history of warp travel and first contact.

During Coon’s tenure, the wider setting became more clearly defined too: the Federation, Starfleet’s authority and the Prime Directive took firmer shape. Those developments involved several writers and earlier ideas, including Roddenberry’s. Coon’s contribution belongs within that collaboration. He helped give the Enterprise a larger society to represent, complete with principles that could become difficult to follow.

He also helped make room for “The Trouble with Tribbles”. David Gerrold wrote the episode, and production records show Coon providing substantial feedback as its premise developed. The result remains a lovely demonstration of how much comedy these characters could carry. Kirk’s mounting exasperation works because we already know how seriously he takes his responsibilities. Put that man under a shower of tribbles and the joke practically takes care of itself.

This is where I think Coon’s contribution to Trek’s lasting popularity becomes especially clear. Viewers could admire the crew’s courage and enjoy their company. The jokes, irritations and friendships gave us reasons to return between the big ideas. A future worth caring about needs people worth caring about inside it.

His run as producer ended during the second season. Accounts of his departure describe a combination of exhausting production demands and differences over the programme’s direction, particularly its comedy. He continued contributing to the third season under the name Lee Cronin.

After Trek, Coon worked on It Takes a Thief and wrote for programmes including Kung Fu and The Streets of San Francisco. He also collaborated with Roddenberry again on The Questor Tapes, a television film about an android seeking answers about his existence. It aired in 1974, after Coon’s death.

Gene L. Coon died on 8 July 1973, aged just 49, from cancer. He never saw Star Trek become a film series, never saw The Next Generation, and never saw how far the characters and ideas he helped develop would travel.

There is something painfully unfair about that. The original series had been cancelled in 1969; its remarkable afterlife grew through syndication and the devotion of its audience. Coon helped create the work that audience kept returning to, but he missed so much of the recognition and expansion that followed.

Star Trek’s success belongs to a great many people: its creator, writers, actors, directors, designers, production crews and the fans who kept it alive. Coon’s place among them is secure in the episodes themselves. Watch Kirk spare the Gorn. Watch Spock reach the Horta. Watch McCoy complain, then get on with helping someone.

Those scenes still have something to say about the kind of people we could become. They are exciting, funny and compassionate, sometimes within the same few minutes. Gene L. Coon understood how to put those qualities on screen together. Six decades later, we are still enjoying the results.
