Ralph Ellison's classic 1952 novel Invisible Man is one of the most important and controversial novels in the American canon and remains widely read and studied. This Companion provides an introduction to this influential and significant novelist and critic and to his masterpiece. It features essays by leading scholars, a chronology and a guide to further reading. The essays reveal alternative dimensions of Ellison's art radiating out from Invisible Man into other domains - technology, political theory, law, photography, music, religion - and recover the compelling urgency and relevance of Ellison's political and artistic vision. Since Ellison's death his published oeuvre has been expanded by several major volumes - his collected essays, the fragment of a novel, Juneteenth (1999), letters and short stories - examined here in the context of his life and work. Students and scholars of Ellison and of American and African-American literature will find this an invaluable and accessible guide.
