Commander Steven Gerber was a Starfleet officer in the 24th century.

In 2365, he was assigned to the USS Yamato. He served under Captain Donald Varley as a first officer. He recorded a number of captain's logs, which were later seen in a list sorted by stardate on Captain Jean-Luc Picard's monitor on aboard the USS Enterprise-D. He was killed when his ship self-destructed. (TNG: "Contagion", okudagram)

He was named after episode co-writer Steve Gerber. (Star Trek Encyclopedia (3rd ed., p. 541))
His first name is spelled two different ways in the list; three times with a "v" and once with a "ph".
