Keller (Fallout 3)

Mr. Keller is part of the Keller Family. He is mentioned in the Keller Family Transcript and it is speculated that his name is John.

Though it is never explicitly confirmed in-game, the G.E.C.K would seem to reveal that the Glowing One at the entrance of the National Guard Depot is Mr. Keller, having an ID of "MisterKellerGlowingOne" in the editor.

This is supported by the Diary of Candace Keller, which notes that he frequently left the safety of the bunker. Ignoring the G.E.C.K. ID, it may also be his son Ralph Keller, who left the bunker to "walk into a mushroom cloud."
