Leonard Nimoy, who portrayed Spock in the original "Star Trek" series, recently attended what he said would be his final convention for the hit sci-fi franchise.

The 80-year-old actor began portraying the character, a half-human, half-Vulcan on the original series, which debuted in 1966. He later reprised his role, who is a friend and colleague to Captain James T. Kirk, played by William Shatner, in movies, including the 2009 "Star Trek" reboot.

At a "Star Trek" convention in Chicago, held to celebrate the franchise's 45th anniversay, Nimoy appeared before fans and spoke about his life and career. He "formed four fingers into a V for Vulcan sign and intoned to fans Spock's most famous phrase: 'Live long and prosper,'" the Associated Press reported, adding that he said the convention would be his last.

"So much to be thankful for," Nimoy Tweeted on Tuesday, October 4. "The video from the Star Trek cast. JJ Abrams.FUNNY. The wave of kindness from the crowd. My family there. LLAP."

Nimoy has often attended "Star Trek" events. In October 2010, Nimoy underwent emergency abdominal surgery for a "minor, benign, abdominal condition" and was forced to cancel appearances at a "Star Trek" convention at an event in his honor at California State University in Long Beach, which was later rescheduled for April 2011.

Nimoy talked to "Star Trek" fan site TrekToday earlier this year about why he keeps doing appearances, when most actors would have retired, and he said it was a "thank you" to his fans.

"I still feel an obligation to be out there for them, to tell them the 'Star Trek' stories and to bring them up to date on what I'm doing, " Nimoy told TrekToday.com. "There's still a lot of interest. I don't know when I will stop doing this. I think there is an end in sight. I will not going on doing it indefinitely, but I am scheduled for three or four events for this year."
