Despite his varied talents, Leonard Nimoy will forever be linked with the logical Mr. Spock. Spotted by “Star Trek” creator Gene Roddenberry when he appeared on Roddenberry’s NBC Marine Corps. skein “The Lieutenant,” Nimoy was offered the role of Spock and co-starred in the 1965 “Star Trek” pilot “The Cage.” NBC execs liked the concept but thought the pilot too cerebral, so they ordered a second pilot of the Desilu production with some script and cast changes (only Nimoy made it through both pilots). The series finally bowed on NBC in the fall of 1966. After three seasons, it was canceled in 1969 but would go on to be a hit in syndication, spawning films and other TV iterations and gaining a huge following of fans known as Trekkers or Trekkies.
