He shot to fame with an article called, â oeThe Celebrated Jumping Frog of Calaveras Countyâ , published in 1865 in his brotherâ (TM)s newspaper.He is perhaps best known for, The Adventures of Tom Sawyer, published in 1876. He wrote The Adventures of Huckleberry Finn as its sequel in 1884. Twain was born shortly after an appearance of Halleyâ (TM)s Comet, and died a day after its next appearance, just as he had predicted.
