Carson Beckett

Biologist and chief medical doctor at Earth's Atlantis base in the Pegasus Galaxy. Beckett was originally assigned as a representative from Scotland to the Ancient Outpost in the Antarctic, where it was discovered that he possessed a rare gene from the Ancients that allows him to use their technology. In fact, it was Beckett who discovered the gene necessary to operate many Ancient devices. Despite the fact that Beckett himself is not especially technologically inclined, Dr. Rodney McKay forced him into the outpost's command chair in the hopes of learning something more about the technology. Beckett accidentally activated a dormant Drone Weapon, but was able to shut it back down before it harmed General O'Neill and Major Sheppard as they traveled toward the base in a helicopter.

A member of the expedition under the command of Elizabeth Weir, Beckett traveled through the Stargate to Atlantis. One of his first duties was to dissect a severed Wraith arm that Sheppard brought back from Athos after the creature's Dart was shot down. His study led to the first insights into Wraith physiology. Beckett later learned even more about Wraith biology when he helped the Hoffans to develop a drug that prevents the creatures from feeding on the life-force of a human victim.
