c. Hartford, CT
Twain was born on Nov. 30, 1835.
His travels took him all over the U.S. and around the world. But it was during his years in Hartford that he seemed to be at him most prolific, rattling off one classic after another including The Adventures of Tom Sawyer, The Adventures of Huckleberry Finn, The Prince and Pauper and A Connecticut Yankee in King Arthur's Court.
The house ceased to be a refuge for him in 1896, when his daughter died there from meningitis. The memories were too painful for him and he could never bring himself to live there again.
