What has the author Gerhardt Cornell Mars written?

There doesn't seem to be a widely recognized author named Gerhardt Cornell Mars. It's possible that:

* The name is misspelled. Double check the spelling.

* The author uses a different name. Perhaps they publish under a pseudonym.

* The author is relatively unknown. They may have written smaller works or be an author in a niche genre.

To help me find the author, could you please provide more information? For example:
