What was Henry fords favorite book?

There is no definitive answer to what Henry Ford's favorite book was. While he was known to enjoy reading and had a library of books, there is no record of him ever publicly stating a favorite.

It's possible that his favorite book was one that wasn't widely known or one that he simply enjoyed reading for personal reasons.

However, we do know that he was interested in books on self-improvement, history, and technology. He also owned a copy of the Bible, which suggests he may have found it important.

Without further information, it's impossible to say definitively what his favorite book was.
