Edward Gray

Dr. Edward Gray was one of RobCo's senior engineers who, before the Great War, planned and supervised the installation of the Graygarden hydroponics facility. He created the Supervisors Brown, Greene and White to make the greenhouse autonomous from human intervention. As an avid television watcher he decided to give TV hosts' personalities to the three supervisors in charge of the greenhouse.

Background
During conversation with Supervisor White the Sole Survivor may respond that they remember him from before the Great War (possibly from a television news feature) and that he was one of RobCo's senior engineers, "but more than a little eccentric".

Appearances
Dr. Edward Gray is only mentioned in Fallout 4.
