The title character, Ravelstein, is based on the philosopher Allan Bloom, who taught alongside Bellow at the University of Chicago's Committee on Social Thought. Remembering Bloom in an interview, Bellow said, "Allan inhaled books and ideas the way the rest of us breathe air. ... People only want the factual truth. Well, the truth is that Allan was a very superior person, great-souled. When critics proclaim the death of the novel, I sometimes think they are really saying that there are no significant people to write about," but "Allan was certainly one."
