LOS ANGELES: Leonard Nimoy, world famous to "Star Trek" fans through a beloved cult TV series and a half-dozen films as the pointy-eared, purely logical science officer Mr. Spock, has died.

Nimoy's son, Adam, says the actor died Friday morning in Los Angeles of end-stage chronic obstructive pulmonary disease. He was 83.

Although Nimoy followed his 1966-69 "Star Trek" run with a notable career as both an actor and director, in the public's mind he would always be Spock.

The famous catchphrase “Beam me up, Scotty” refers to the transporter device, which was often operated by chief engineer Montgomery Scott during the original series.
