Nichelle Nichols, who played Lt Uhura in original Star Trek, dies aged 89

Nichelle Nichols, who played communications officer Lt Nyota Uhura on the original Star Trek series and helped to create a new era for television in the 1960s, has died in New Mexico at the age of 89.

Nichols’ son, Kyle Johnson, announced her death on Sunday via Facebook, saying: “I regret to inform you that a great light in the firmament no longer shines for us as it has for so many years.” Nichols’s death, on Saturday night in Silver City, was later confirmed by her agent.

Johnson said his mother had succumbed to natural causes, seven years after suffered a stroke.

“Her light however, like the ancient galaxies now being seen for the first time, will remain for us and future generations to enjoy, learn from and draw inspiration.”

Nichols will be remembered chiefly for her role in the sci-fi adventure series, but she began her career as a dancer and nightclub singer.

Co-star George Takei tweeted that his heart was heavy, “my eyes shining like the stars you now rest among, my dearest friend” and he would have more to say soon on the “incomparable” trailblazer.

Prominent Georgia Democrat and voting rights organizer Stacey Abrams, who is running again for the state governorship and is a longtime Star Trek fan, tweeted a picture of herself with Nichols.

“One of my most treasured photos – Godspeed to Nichelle Nichols, champion, warrior and tremendous actor. Her kindness and bravery lit the path for many,” she wrote. “May she forever dwell among the stars.”

Star Trek brought Nichols enduring recognition and helped to break down some racial barriers in the television business, as they were rampant elsewhere.

She shared one of the first lip-to-lip interracial kisses on television – with co-star William Shatner, aka Captain Kirk. The kiss at the time was considered a forward-looking move on the part of the actors, as well as Star Trek creator Gene Roddenberry and the network that broadcast the show, NBC.

The episode in question, titled Plato’s Stepchildren, aired in 1968 and was fashioned in a way that gave those involved something of an out from any potential discriminatory backlash: Uhura and Kirk did not choose to kiss but were instead made to do so after being inhabited by aliens.

Roddenberry had reportedly insisted on an integrated crew for Starship Enterprise – a bold move given that interracial marriage was still illegal in 17 US states. Only a year earlier, Variety reported, Sammy Davis Jr had gone no further than kiss Nancy Sinatra on the cheek on Movin’ With Nancy.

The original Star Trek premiered on NBC on 8 September 1966. Its multicultural, multiracial cast was creator Gene Roddenberry’s message to viewers that in the far-off future, the 23rd century, human diversity would be fully accepted.

“I think many people took it into their hearts … that what was being said on TV at that time was a reason to celebrate,” Nichols said in 1992 when a Star Trek exhibit was on view at the Smithsonian Institution.

She often recalled how civil rights leader Martin Luther King Jr was a fan of the show and praised her role.

She met him at a civil rights gathering in 1967, at a time when she had decided not to return for the show’s second season.

“When I told him I was going to miss my co-stars and I was leaving the show, he became very serious and said ‘You cannot do that’,” she told The Tulsa World in a 2008 interview.

“‘You’ve changed the face of television forever, and therefore, you’ve changed the minds of people’,” she said the civil rights leader told her.

Nichols said: “That foresight Dr King had was a lightning bolt in my life.”

More recently, she had a recurring role on television’s Heroes, playing the great-aunt of a young boy with mystical powers.

Nichols, trained as a dancer and also worked as a nightclub chanteuse, with the Washington Post reporting that she thought being cast in Star Trek would be a “nice stepping stone” to Broadway stage fame, not realizing that the TV show and her character would be an iconic and enduring smash hit.

Actor Wilson Cruz wrote on Twitter that “representation matters”.

Nichols “modeled it for us. With her very presence and her grace she shone a light on who we as people of color are and inspired us to reach for our potential,” he wrote. “Rest well, glittering diamond in the sky.”

The Smithsonian tweeted a picture of Lt Uhura’s iconic red mini-dress and noted that Nichols made “history for African American women in TV and film. Nichols also volunteered to recruit women and people of color for Nasa.”

Nichols was born Grace Dell Nichols in Robbins, Illinois, on December 28 1932. According to the National Space Society, she sang as a 16-year-old with jazz great Duke Ellington – her career getting under way at an early age – in a ballet she created, and later joined his band.

Her big break in the 1961 Chicago musical Kicks and Co. Nichols later appeared in the title role in Carmen Jones and in a New York staging of Porgy and Bess as well as in Jean Genet’s The Blacks, and landed small film roles.

Nichols was married and divorced twice, and is survived by her son, Kyle Johnson.
