Susan Bay Nimoy, the second wife of the late “Star Trek” actor Leonard Nimoy, is an American actress who appeared briefly in the “Star Trek: Deep Space Nine” television series in the mid-1990s. The 71-year-old performer, who married Nimoy in 1989, is a former model with a famous director cousin, Michael Bay, whose films include blockbusters such as “Armageddon,” “Pearl Harbor” and “Transformers.”

Susan Nimoy was born as Susan Linda Bay in Los Angeles March 16, 1943. Her best-known movies include 1963’s “The Skydivers,” 1967’s “The Big Mouth” and 2009’s “Mother and Child.” She currently serves on the board of directors for the nonprofit organization Foundation for National Progress, which publishes the online Mother Jones, a media outlet that “specializes in investigative, political, and social-justice reporting.” As a model, she appeared in a book of nude photographs taken by her husband meant to celebrate Judaism.

Susan Nimoy is the stepmother of Leonard Nimoy’s children, Adam Nimoy and Julie Nimoy. Before marrying Nimoy, Susan Nimoy was previously wedded to John Schuck, an actor who appeared in a couple of “Star Trek” films alongside her second husband. Schuck is also known for his roles in the film “MASH,” the television series “The Munsters Today” and the movie “The Curse of the Jade Scorpion.” (Leonard Nimoy’s first wife was the now-deceased actress Sandra Zober.)

Susan Nimoy confirmed her husband’s death Friday, according to the New York Times. She said the actor’s cause of death was chronic obstructive pulmonary disease, one of the most common lung diseases brought on by smoking. Leonard Nimoy died at the couple’s home in Los Angeles at the age of 83.

The science-fiction icon tweeted about his condition last year. “Smokers, please understand: If you quit after you’re diagnosed with lung damage, it’s too late. Grandpa says learn my lesson: Quit now,” he said. “I’m doing OK. Just can’t walk distances. Love my life, family, friends and followers.”
