Samuel Langhorne Clemens (November 30, 1835 – April 21, 1910), known by his pen name Mark Twain, was an American writer, humorist, entrepreneur, publisher, and lecturer. He was lauded as the "greatest humorist this country has produced", and William Faulkner called him "the father of American literature".

I am quite sure . . . I have no race prejudices, and I think I have no color prejudices, nor caste prejudices, nor creed prejudices. Indeed, I know it. I can stand any society. All I care to know is that a man is a human being — that is enough for me; he can't be any worse.
