Star Trek's Lieutenant Uhura played by Nichelle Nichols. As a girl, seeing such an intelligent, beautiful black woman on television let me know the future held a place for me and all people of color. Thank you Nichelle Nichols and Octavia Butler.
Mark Lenard played a Vulcan ambassador and a Romulan commander. Correspondence courses on Vulcans are available via the Vulcan Orientation College and on Romulans via the Romulan Orientation College in Starfleet Academy Institute of Alien Studies.
