#53: Mark Twain
The Adventures of Tom Sawyer and Adventures of Huckleberry Finn made Mark Twain America’s most famous writer. He grew wealthy from his books and lectures. But he couldn’t resist a good invention, and he sank a fortune into a new typesetting machine that he was sure would change printing forever.

It never worked well enough, and his publishing company also collapsed. In 1894, Twain went bankrupt. Instead of hiding, he set off on a lecture tour around the world. He paid back every creditor in full, even though the law did not require him to.
