However, there are a few possibilities:
* A typo: You might have made a typo. Double-check the name. Perhaps you meant "Irving Howe" or "Irvin Zeitlin"?
* Less known author: It's possible the author is less known or published under a different name.
* Fictional character: The name could belong to a character in a book or film.
To help me find the correct author, please provide more context, such as:
* Any books or articles you know they wrote
* Their field of expertise
* Any other information you know about them
With more information, I can hopefully identify the author you're looking for.
