After being rushed to the hospital on February 19, the New York Times is now reporting that legendary Star Trek actor Leonard Nimoy has died at age 83 on Friday, February 27.

The actor was diagnosed with Chronic obstructive pulmonary disease (COPD) in 2014, three decades after giving up cigarettes. He discussed his history with smoking on CNN’s Piers Morgan Tonight early last year:

Nimoy, who first appeared as half-Vulcan, half-human science officer Spock in 1965, most recently wore the famous pointed ears in 2013’s Star Trek Into Darkness. His last major television appearance was in the role of mysterious and unscrupulous scientist William Bell on FOX’s Fringe, a role he reprised several times through 2012.

He retired from the Star Trek convention circuit in more than three years ago, last appearing at Creation Entertainment’s Chicago con in October 2011, though he did continue to attend shows remotely via Skype webcasts as recently as this past summer.

Leonard Nimoy is the third member of the original Star Trek cast to pass on, after DeForest Kelley in 1999 and James Doohan in 2005. He is survived by his wife of 26 years, Susan Bay, as well has his children Adam and Julie Nimoy.
