He was an American novelist, essayist, and literary critic, best known for his 1952 novel *Invisible Man*. He is considered one of the most important writers of the 20th century, and his work explored themes of race, identity, and the American experience.
However, other writers with the last name Ellison exist, though they might not be as well-known. It would be helpful to have more context to know which Ellison you're looking for. For example:
* Are you looking for a specific genre of writing? (fiction, non-fiction, poetry, etc.)
* Are you looking for a writer from a specific time period?
* Do you have any other information about the writer, such as their first name or a specific work?
Providing more information will help me give you a more accurate answer.
