"LLAP" stands for "Live long and prosper," a phrase commonly uttered by Spock.
In addition to the "Star Trek" television series, which first aired in 1966, Nimoy played his signature role in eight movies, the latest being 2013's "Star Trek Into Darkness." He also directed two "Star Trek" films and the 1987 comedy "3 Men and a Baby."
Nimoy's first film credit came in the 1951 film "Queen for a Day." He also acted in episodes of popular television series including "The Twilight Zone," "General Hospital" and "Gunsmoke." Recently, he had a recurring role on Fox's science-fiction series "Fringe."
Early in his career, Nimoy, born to two Jewish immigrants from Ukraine, served in the United States Army Reserves. He was honorably discharged in 1955 after attaining the rank of sergeant.
After "Star Trek" took off, Nimoy released four music albums in the 1960s. His second record, "Two Sides of Leonard Nimoy" included the song "The Ballad of Bilbo Baggins," which has since become a cult classic.
He also published 12 books, including a pair of autobiographies and seven volumes of poetry. Nimoy's most recent book, 2010's "Secret Selves," was a collection of his own photography.
Leonard Nimoy is survived by two children and his wife Susan.
