Kulp did the signal work in the kernel and added the code to the c shell
to use it (or had Eric Cooper, who was working for him as a student at
the time do fg/bg). He did his work on 3BSD and set the mods to Berkeley,
where Joy took them and integrated them into 4.1 BSD.
As far as I can tell, Kulp has always gotten credit for doing the initial
work, Joy for the `standard' BSD integration, and David Korn for doing
the second (non-csh) implementation.

Huh, I too thought Bill Joy did it. Did he integrate it and get credit
that way? (describing MIT's job control that Joy
swiped
and added to BSD),
The original concepts might have come from MIT, but the BSD implementation
was done by Jim Kulp at IIASA before it was folded into 4.1 BSD.
