Leonard Nimoy Dies

Nimoy died in Los Angeles after a battle with a lung disease called chronic obstructive pulmonary disease. Though he had quit smoking 30 years ago, Nimoy was checked into UCLA Medical Center last week after suffering intense chest pains.

When Nimoy was a struggling actor in the mid 60s, he landed the part of Mr. Spock on the Star Trek TV series that debuted in 1966. He reprised the role in the Star Trek films, even playing an aged Spock in the two recent reboots starring Zachary Quinto as the younger version of his character and Chris Pine in the role of Captain Kirk, which was originated by William Shatner.

In his last tweet, which was written on Sunday, Nimoy made reference to Spock’s famous line, “Live long and prosper.”

Following his initial run in Star Trek, Nimoy starred on TV series Mission Impossible and in the TV drama A Woman Called Golda with Ingrid Bergman, for which he received an Emmy nomination. In the 70s, he also narrated the docu-series In Search Of. More recently, he appeared on TV in Fringe.

On the theater stage, Nimoy appeared in A Streetcar Named Desire, Cat on a Hot Tim Roof, Fiddler on the Roof, The King and I, My Fair Lady and Equus.

Outside of acting, Nimoy penned poetry books, recorded albums and released two autobiographies.
