Aaron Brown

Doctor Aaron Brown was a human scientist in the 23rd century and was a long-time assistant of Dr. Roger Korby.

Aaron Brown had worked with Dr. Korby for many years, and accompanied him on many archaeological expeditions. In 2259, Brown accompanied Korby on an expedition to Vestalan along with Christine Chapel. Brown became good friends with Christine, and she often referred to him as "Brownie", and he was happy when Korby and Chapel were engaged. (TOS short story: "Snake Pit!" and episode: "What Are Little Girls Made Of?").

In 2261, Brown accompanied Korby on an expedition to Exo III. During the mission their ship crashed, and Brown was killed instantly. Korby survived long enough to encounter the android Ruk and manage to create an android duplicate of himself. The android Korby later created a duplicate of Brown which continued to serve him. However, the android Brown was less emotional than the real Brown, and when the USS Enterprise arrived in 2266, Christine soon discovered that the android wasn't Brown and led to the downfall of Korby's plan to recreate the Federation with androids. (TOS episode: "What Are Little Girls Made Of?").

The android Brown was deactivated by James T. Kirk after he shot him with a phaser. Brown was later recovered by Dr. Emil Vaslovick and kept in his collection on Valhalla into the 24th century. (TNG novel: Immortal Coil).

Even though the original android was deactivated in 2266, another duplicate was activated in 2268 and sent out a distress call which brought the USS Hood to Exo III. Using an android duplicate of Captain Kirk, Brown was able to take control of the Hood by replacing Captain Joaquin Martinez and the senior staff with androids, and set about trying to make Korby's dream a reality. Thankfully, Brown and his androids were stopped by the Enterprise and the USS Potemkin. (TOS novel: Double, Double).
