were modest, that turned around with Herzog. Bellow continued teaching well into his old age, enjoying its human interaction and exchange of ideas. He taught at Yale University, University of Minnesota, New York University, Princeton University, University of Puerto Rico, University of Chicago, Bard College and Boston University, where he co-taught a class with James Wood ('modestly absenting himself' when it was time to discuss Seize the Day). In order to take up his appointment at Boston, Bellow moved in 1993 from Chicago to Brookline, Massachusetts, where he died on April 5, 2005, at age 89. He is buried at the Jewish cemetery Shir HeHarim of Brattleboro, Vermont. While he read voluminously, Bellow also played the violin and followed sports. Work was a constant for him, but he at times toiled at a plodding pace on his novels, frustrating the publishing company.

Bellow's son by his second marriage, Adam, published a nonfiction book In Praise of Nepotism in 2003. In 2000, when he was 84, Bellow had his fourth child and first daughter, with Freedman. When he was married to his second wife Tschacbasov, his father-in-law was artist Nahum Tschacbasov. Themes and style Bellow's themes include the disorientation of contemporary society, and the ability of people to overcome their frailty and achieve greatness or awareness.

Principal characters in Bellow's fiction have heroic potential, and many times they stand in
