The LAFD has confirmed paramedics responded to a medical call at the Bel-Air home of Leonard Nimoy at 7:31 a.m. on Thursday, February 19 and he was transported to UCLA Medical Center. After Star Trek“s three-season run on NBC, the show took on a whole new life in syndicated reruns. This proved to be a double-edged sword for Nimoy, who wrote of his frustrations with being typecast in his autobiography I Am Not Spock. Once Star Trek was revived for the big screen in a series of movies, Nimoy reinvented himself as a director, helming Star Trek“s III and IV as well as such hits as Three Men and a Baby. In recent years, Nimoy reprised the role of Spock in J.J. Abrams” Star Trek reboot, and also guest starred in a recurring guest star role on the Fox sci-fi series Fringe. According to reps for the Hollywood Walk of Fame, flowers will be placed on Nimoy’s star at 10:30 a.m. PT this morning.

We will all miss his humour, his talent and his capacity to love.”; Nichelle Nichols, Captain Nyota Uhura on “Star Trek”;, on the passing of her co-star: “I am deeply saddened by the death of my dear friend Leonard Nimoy. But, I also want to celebrate his extraordinary life. He was a true force of strength and his character was that of a champion. Leonard’s integrity and passion as an actor and devotion to his craft helped transport Star Trek into television history. His vision and heart are bigger than the universe. I will miss him very much and send heartfelt wishes to his family.”; Steve Guttenberg released this statement: “Leonard Nimoy was smart, warm and had a personality that made everyone feel comfortable. He was a talented actor, director, poet and photographer. But his most enduring quality was his kindness and his desire to make you the most you could be. Like everyone who knew or knew of him, I will miss him.”; Prior to his passing, Nimoy sent out this poignant final tweet: B-3m5hCUIAIpVa6 And Nimoy’s grandson posted a tweet from the late actor’s Twitter account on Friday:
