It's hard to overstate the influence of Mark Twain. Ernest Hemingway once wrote, "All modern American literature comes from one book by Mark Twain called Huckleberry Finn," and many critics now cite this work as the first "Great American Novel."
While the majority of those in the English-speaking world have heard of Mark Twain, and his two most famous novels, The Adventures of Tom Sawyer and Adventures of Huckleberry Finn, they may not know as much about this classic American author as they may think. To start with, Mark Twain is not even his real name.
