Moses E. Herzog
The protagonist and namesake of the novel, whose name Bellow borrowed from a minor character in James Joyce's Ulysses. Herzog is a womanizing, self-loathing, idealistic, and scholarly man in his mid-forties, enduring a difficult second divorce and a resulting depression. The story is told from inside of Moses' head; one might say the book is not so much about Herzog as it is Herzog.
