Leonard Nimoy – Cause of Death, Movies, Net Worth and Full Biography
On February 27, 2015, the world lost one of science fiction’s most recognisable figures. Leonard Nimoy, the actor who brought the logical, half-Vulcan Spock to life, died at his home in Bel Air, Los Angeles, at the age of 83.

Nimoy publicly announced his COPD diagnosis in January 2014, saying, “I quit smoking 30 years ago. Not soon enough.” He had started smoking as a teenager and was a two‑pack‑a‑day smoker by high school. He quit in 1985 after his daughter Julie warned him about secondhand smoke, but the damage was done. According to his family – widow Susan Bay Nimoy and son Adam Nimoy – and confirmed by reports from the New York Times and BBC News, he was hospitalised shortly before his death, fell into a coma on February 25, and died the following morning at his Bel Air home.
End‑stage COPD is a progressive lung disease that severely limits breathing. Nimoy’s case was directly linked to his long‑term smoking habit. For reliable medical information, see the American Lung Association.

For a full list of his screen credits, see Leonard Nimoy: A Complete Filmography.

What was Leonard Nimoy’s net worth, height, and other personal details?
At the time of his death, Nimoy’s net worth was estimated at $45 million by multiple sources, though no official public document confirms this figure. His height has been reported as 6 ft 1 in (1.85 m). Because neither value appears in official records, some uncertainty remains around the exact numbers.
Nimoy was born Leonard Simon Nimoy on March 26, 1931, in Boston, Massachusetts, to Jewish immigrant parents Dora Spinner and Max Nimoy. He began acting with a bit part in Queen for a Day (1951) and married Sandra Zober in 1954; they had two children, Julie and Adam. He later married Susan Bay Nimoy.

How did Leonard Nimoy become famous as Spock in Star Trek?
Nimoy was cast as Spock in 1966 for the original Star Trek series. The character – a half‑human, half‑Vulcan first officer who prized logic above emotion – became a cultural phenomenon. Nimoy initially struggled with being typecast, writing the autobiography I Am Not Spock (1975). But he later reconciled with the role, publishing I Am Spock (1995) and embracing the character’s impact.
Spock’s signature salute and the phrase “Live long and prosper” (translated from Vulcan) became lasting symbols of Star Trek fandom. An asteroid, 4864 Nimoy, was named after him in June 2015. Documentary films by his children – For the Love of Spock (2016) and Remembering Leonard Nimoy (2017) – further explore his legacy. The Nimoy Foundation (formerly the Nimoy Knight Foundation) supports COPD awareness and research, a cause close to his heart.
