Ensign Hedrick was a crewmember aboard the USS Enterprise-D in the 2360s.
In 2367, he was the on duty transporter chief when Geordi La Forge overwhelmed him and beamed down to the surface of the planet Tarchannen III. Later, Hedrick informed Commander Riker over com that he had determined La Forge's transport coordinates after he had beaned down to the surface. (TNG: "Identity Crisis")
Hedrick was played by stunt coordinator Dennis Madalone and was listed as "Transporter Technician" in the end credits of the episode. His name comes from the script, call sheets, and the Star Trek: The Next Generation Companion (2nd ed., p. 158).
In the cast list from the fourth draft script of "Identity Crisis", he was referred to as "Transporter Tech Hedrick". However, in the cast list from the final draft of the episode's script, he was referred to as "Transporter Chief Hedrick". [1]
The Star Trek Encyclopedia misspells his name as "Hendrick", which was also the spelling used in the episode's closed captioning.
