M’Benga was a physician from Uganda (presumably a member state of the United States of Africa) on Earth who served on the USS Enterprise during the late 2260s. He did his medical internship on Vulcan and was something of an expert in diagnosing and treating Vulcans.
Dr. M’Benga was seen in the TOS episodes “A Private Little War” and “That Which Survives”. He was played by record producer, Motown executive, and actor Booker Bradshaw. The character returned to Trek in the fan series “Star Trek Continues” with Martin Bradford portraying the physician in the episodes “Divided We Stand” and “To Boldly Go, Part I”.
