Wesley Crusher is a character in the television series Star Trek: The Next Generation. Played by actor Wil Wheaton, the character was a regular for the first four seasons. Afterwards, the character appeared sporadically. The character also appeared briefly in Star Trek Nemesis. He is Beverly Crusher's son.
In the television series Star Trek: The Next Generation, the character of Wesley Crusher first arrived on the Enterprise-D with his mother, soon after Captain Jean-Luc Picard assumed command. Captain Picard was annoyed by Crusher at first, as Picard is uncomfortable around all children, but he comes to realize that Crusher understands many things beyond his age and has inherited his mother's high intelligence.
An alien Traveler expressed to Captain Picard, and was also told not to tell Dr. Crusher, that Wesley had a unique intelligence and great potential if provided encouragement and opportunity, comparing him to a child prodigy like Mozart. Picard soon appointed Crusher to an acting ensign.
In early episodes of the series, Picard did not allow Crusher on the bridge of the ship. Crusher eventually took the entrance exam for Starfleet Academy. His test score ranked lower than expected, and he was not accepted into the Academy in his first attempt. ("Coming of Age"). Later he missed his second chance to take the Academy entrance exam in order to assist the Enterprise-D crew in rescuing Will Riker, Deanna Troi, and Lwaxana Troi from hostile Ferengi. Picard soon granted him a field promotion to full ensign ("Ménage à Troi").
