Leonard Nimoy, the beloved actor who famously portrayed Spock in the Star Trek film and television franchise, has died at the age of 83. According to his wife, the cause was end-stage chronic obstructive pulmonary disease. He passed away Friday at his home in the Bel Air section of Los Angeles.

Nimoy earned three Emmy Awards for portraying the half-Vulcan, half-human Spock on the Star Trek original television series, which aired between 1966 and 1969. In addition to voicing the character on Star Trek: The Animated Series in the early ’70s, he reprised the role in the first six Star Trek films. He directed two of those movies himself, including 1986’s Star Trek IV: The Voyage Home, the second highest grossing film in the franchise to date. He also lensed Three Men and a Baby, the highest grossing film of 1987.



Nimoy enjoyed a career working in numerous genre shows, including the original Mission: Impossible TV show, the documentary series In Search Of…, and most recently Fringe. He also provided the voice of two Transformers: Galvatron in the animated classic The Transformers: The Movie and Sentinel Prime in Transformers: Dark of the Moon.

Most recently, he played the elder Spock Prime in the 2009 Star Trek reboot as well as its 2012 sequel, Star Trek Into Darkness, acting as the connecting thread between the original series and the parallel universe of J.J. Abraham’s version.

Below, read Nimoy’s touching final tweet, which he signs with the abbreviation of Spock’s cherished catchphrase, “Live long and prosper.”

A life is like a garden. Perfect moments can be had, but not preserved, except in memory. LLAP — Leonard Nimoy (@TheRealNimoy) February 23, 2015
