Actor Leonard Nimoy, best-known as the iconic Mr. Spock of "Star Trek," died Friday at the age of 83.

Nimoy's wife, Susan Bay Nimoy, said his cause of death was end-stage chronic obstructive pulmonary disease. Nimoy himself thought the disease was brought on by his smoking habit, which he had quit roughly 30 years ago.

He tweeted a little more than a year ago about his diagnosis with the disease.

He used the diagnosis as an opportunity to warn others about the long-term dangers of smoking.

And just last month, Nimoy again tweeted his regret over smoking, signing off his message with his trademark "LLAP" or "live long and prosper."
