Wesley Crusher is the son of Dr. Beverly Crusher and the late Lt. Cmdr. Jack Crusher. While growing up, Wesley was more advanced than other children his age and he had few friends. Wesley has strong mathematics, engineering and propulsion skills, which he refined on the U.S.S. Enterprise NCC-1701-D while his mother served as CMO. In 2364, the Traveler from Tau Alpha C told Captain Picard that Wesley was a genius, and Picard gave him a field promotion to Ensign for his service to the ship. In 2370, Wesley left Starfleet Academy to learn the ways of the Traveler on Dorvan V.
