What man was not a business tycoon in late nineteenth-century America?

One notable figure who was not a business tycoon in late nineteenth-century America is Mark Twain. While he was a prolific author and humorist, Twain did not amass wealth through industry or commerce like many of his contemporaries. Instead, he focused on literature, social commentary, and lecturing, which often placed him at odds with the business practices of the time. Despite his financial struggles, Twain's contributions to American literature remain significant.
