Susan Calvin
Robopsychologist
1 book · 1950First appears in I, RobotIsaac Asimov's Robot stories gave us the Three Laws of Robotics, and his Foundation saga follows the fall of a Galactic Empire and Hari Seldon's plan to shorten the dark age that follows. Late in life he tied the two series together.
Best estimate, compiled from series guides, publisher descriptions and reviews where available, and from memory otherwise. Book level only, not chapter level. Minor includes cameos and brief references. Each book carries a confidence rating in its tooltip. I, Robot is a story collection; Susan Calvin links most of its tales. Prelude to Foundation and Forward the Foundation are prequels.
