Bob Anderstein

 was a character heard on the Oscar Zulu radio station.

Background
His son is dying, and is requesting a doctor to come to their sewer hideout. The player can go to help out, only to find out the whole family is long gone. It is likely they put that signal on the air just after the bombs fell. You can see the parents skeletons on the floor.. but not the boy.

Appearances
is only heard in Fallout 3.
