When Star Trek premiered on NBC in September 1966, it brought something television had rarely seen before — a vision of the future where women stood alongside men on the bridge of a starship. Over its three-season run from 1966 to 1969, the show featured a parade of female characters, both recurring and guest, who were bold, striking, and far more complex than the era’s typical TV women. Some became icons. Others faded from the spotlight under difficult circumstances. All of them left a mark on the show’s history.
Among the earliest and most recognizable faces aboard the USS Enterprise was Yeoman Janice Rand, played by Grace Lee Whitney. She served as Captain Kirk’s personal aide, appearing in the first season as a loyal and capable crew member. Whitney brought a grounded warmth to the role that stood apart from the more exotic guest characters the show frequently introduced.
Behind the scenes, Whitney was battling alcoholism, and her character was written out of the show before the first season ended. She later returned to the Star Trek universe in several of the feature films, with DeForest Kelley playing a key role in helping her find work again. Her story is one of the more candid reminders that the world behind the camera was often far messier than the one in front of it.
Majel Barrett took a different path into the Star Trek world. She had originally been cast as the ship’s unnamed first officer in the unaired pilot, but network executives pushed back on the idea of a woman in that role. She was recast as Nurse Christine Chapel for the series — a recurring character who appeared throughout all three seasons. Barrett was also the wife of series creator Gene Roddenberry, a fact that became public knowledge over time.
The Season 1 episode “Mudd’s Women” introduced three women brought aboard the Enterprise by the scheming con man Harcourt Fenton Mudd. The episode was one of the show’s most overt explorations of beauty, manipulation, and gender — and it featured some genuinely memorable guest performances. Karen Steele, who had already earned serious film credentials with her role in the 1955 Oscar-winning drama Marty, played one of Mudd’s women with a quiet confidence that set her apart.
Also appearing in “Mudd’s Women” was Maggie Thrett, who had a brief singing career before landing the role. Her time in the spotlight was cut short after a near-fatal motorcycle accident that forced her away from acting. Sherry Jackson, best known to audiences as the eldest daughter on The Danny Thomas Show, made her Star Trek appearance as Andrea — an android character in the episode “What Are Little Girls Made Of?” Her turn as the robotic but visually striking Andrea was a sharp departure from her wholesome TV image. That same year, Jackson appeared in Playboy and filmed a nude scene for the movie Gunn (1967), though the scene was cut from the American release.
Marianna Hill played Lt. Helen Noel in the Season 1 episode “Dagger of the Mind,” one of the series’ darker psychological stories. Her character, a psychiatrist assigned to accompany Kirk on an investigation of a penal colony, was given real professional weight — she wasn’t just set dressing.
Susan Oliver appeared as Vina in the original unaired pilot, “The Cage,” and her footage was later woven into the two-part episode “The Menagerie.” Her role required her to transform into multiple illusions, including a green-skinned Orion slave girl — one of the most enduring images in all of Star Trek history. Susan Denberg, a German-born actress and Playboy’s Playmate of August 1966, starred in the episode “Metamorphosis” and had previously appeared in the Hammer horror film Frankenstein Created Woman (1967). Her accent was dubbed for that film, reflecting the entertainment industry’s habit of reshaping actresses to fit its preferred mold.
Barbara Anderson appeared as Lenore Karidian in “The Conscience of the King,” one of the more dramatically complex episodes of the series. Her character carried a dark secret, and Anderson delivered a performance that went well beyond the typical guest role. Emily Banks played Yeoman Tonia Barrows in “Shore Leave,” an episode that gave her character room to be playful and expressive — a lighter presence compared to some of the more serious roles on the show.
Venita Wolf appeared in Episode 17, “The Squire of Gothos,” as part of the eccentric Trelane’s drawing room fantasy. Her role was brief, but her look fit the show’s visual style perfectly — polished and otherworldly at the same time.
Madlyn Rhue took on one of the series’ most layered female roles as Lt. Marla McGivers in “Space Seed” — the episode that introduced Khan Noonien Singh. Her character, a historian with a deep fascination for strong historical leaders, chose to side with Khan over her own crew. It was a morally complicated arc, and Rhue handled it with precision.
Lesley Parrish played Lieutenant Carolyn Palamas in “Who Mourns for Adonais?” — an episode where the Greek god Apollo takes the Enterprise crew captive and singles out her character for his affections. Parrish brought a quiet strength to the role, particularly in the scene where she rejects Apollo despite real emotional conflict.
Real-life twins Alyce and Rhea Andrece played the Alice androids in the Season 2 episode “I, Mudd,” a return appearance by the show’s favorite con man. The casting of actual twins added a genuine uncanny quality to the android characters that no amount of special effects could have replicated.
Elinor Donahue, widely known as Betty Anderson from Father Knows Best, appeared as Federation Commissioner Nancy Hedford in “Metamorphosis.” Her character arrives aboard a shuttlecraft critically ill, only to become part of one of the series’ more unusual love stories. It was a significant departure from her previous wholesome TV persona. Angelique Pettyjohn rounds out this gallery as Shahna in “The Gamesters of Triskelion” — a role that required physicality, presence, and a costume that became one of the most recognizable in Trek history. Pettyjohn was a natural fit for the role of a gladiatorial drill thrall, and her silver-haired look made her one of the most visually striking guest stars of the entire series.
