This discusses work of Leites, Berezin, Manin, Kac and others who used some of Grothendieck's concepts to introduce supermanifolds. The good reference is the two-volume work of Deligne, Witten and others published by the AMS around 1998. Nothing original will be stated. Deligne's claim that a consistent set of sign conventions exists will not be checked.
