Saul Bellow, a writer who was often photographed in front of shelves full of books, has died aged 89.

Bellow's protagonists were often introspective intellectuals, and he himself taught at the University of Chicago and Boston University, after initially studying anthropology. He won the National Book Award three times, and then in 1976 the Nobel prize for literature. Philip Roth once compared Bellow to Melville, Hawthorne and Twain.

He didn't write any books you'll have heard of.
