Logicomix, by Apostolos Doxiadis and Christos H. Papadimitriou

A graphic biography of philosopher/mathematician/logician Bertrand Russell and his quest to solve all of logic's unanswered questions.  While primarily historical, liberties have been taken in order to tighten the narrative.

An unlikely success, part of the growing body of ambitious graphic nonfiction that's being published these days.
