Peter Bogert 1300-1500

Dr. Peter Bogert was second in command after Alfred Lanning, he is many times characterized as trying to seize position from Lanning. He is, however, a brilliant mathematician and is many times successful in the novels where he is featured, mainly those with Susan Calvin as main character. In "Liar!", he asks the robot if Lanning is about to retire, and the robot says yes, and that Bogert is the obvious successor. Bogert uses this to increase his power on the plant, but Lanning gets enraged by this sudden change in hierarchy and makes sure Bogert understands who is in charge.
