James Doohan, the burly chief engineer of the Starship Enterprise in the original "Star Trek" TV series and motion pictures who responded to the apocryphal command "Beam me up, Scotty," died early Wednesday. He was 85.

Doohan died at 5:30 a.m. (1330 GMT) at his Redmond, Washington, home with his wife of 28 years, Wende, at his side, Los Angeles agent and longtime friend Steve Stevens said. The cause of death was pneumonia and Alzheimer's disease, he said.
