Leonard Nimoy, the actor who played Spock on Star Trek, died Friday. He was 83 and had lung disease, the New York Times reports.

Nimoy was most famous for his role as the Vulcan Spock on the Star Trek TV show in 1966. He would also later appear in J.J Abrams’ Star Trek reboot movies.

“In Spock, I finally found the best of both worlds: to be widely accepted in public approval and yet be able to continue to play the insulated alien through the Vulcan character,” he once wrote of playing the role.
