Lieutenant Barnaby was a Human male who served as a Starfleet officer during the late-24th century.


In 2370, Barnaby was serving as a security officer on the USS Enterprise-D when he, along with other members of the crew, transported down to a rogue Borg planet in search of Lieutenant Commander Data who had unknowingly been captured by his android brother Lore.

After searching the planet, Barnaby was one of the last to return to the ship, where he relieved Ensign Taitt at the tactical station. He served in that position under the temporary command of Doctor Beverly Crusher due to many of the senior staff still being on the planet.

Due to the presence of a rogue Borg ship in orbit, the Enterprise was forced to abandon the planet temporarily. Barnaby later implemented a plan to drop out of warp as close to the planet as possible in order to rescue the few remaining crew members of the search party, making the precise calculations needed to ensure success.

Initially, he was skeptical of Ensign Taitt's abilities due to her lack of experience, but she soon proved herself after coming up with an experimental plan to successfully destroy the Borg ship using a solar fusion eruption, thereby allowing them to safely rescue the crew from the planet. (TNG: "Descent, Part II")

Background information[]

Barnaby was played by recurring Star Trek guest actor James Horan who also played the role of Jo'Bril in "Suspicions", a Takaran scientist who attempted to steal the very metaphasic shielding technology later used in "Descent, Part II", and in doing so endangered the life of Doctor Crusher. When Crusher discussed the technology with Barnaby in "Descent, Part II", he replied, "I know about that research."

In an interview with, Horan commented that he found acting in makeup easier than without, as, "the character is sort of made for you when you're wearing that mask." [1]

During production, the character was rumored to become a recurring one. Ultimately, this never materialized. [2]

The script for "Descent, Part II" describes Barnaby as, "an older, seasoned veteran." [3]

At one point, his biography gave his first name as Barthalomew. [4](X) This imformation has since been removed.
