Star Trek

The Star Trek actor died Friday in Los Angeles, and NPR TV Critic Eric Deggans says Nimoy's signature role taught fans the power of accepting their differences rather than fighting them.

As Mr. Spock on Star Trek, the late Leonard Nimoy embodied the conflicts faced by many biracial and other people of color. Even on the diverse crew of the Enterprise, he stood out.

The cause was end-stage chronic obstructive pulmonary disease, his granddaughter tells NPR.
