Looking for books about wealthy people who succeeded ethically

I’m looking for book recommendations (ideally biographies or true stories) about people who became very wealthy while acting with integrity. For years I’ve struggled with the idea that wealthy people are inherently selfish, manipulative, or lacking in empathy, and I want to challenge that assumption.

I’m interested in books about individuals who built significant wealth without deceiving others, stepping on people, or compromising their values, people who were successful and still good, ethical human beings. Biographies, well-researched profiles, or other true-life accounts are welcome.

Does anyone have recommendations?
