Mark Twain was born Samuel Langhorne Clemens in 1835. He gained national attention as a humorist in 1865 with the publication of "The Celebrated Jumping Frog of Calaveras County," but was acknowledged as a great writer by the literary establishment with The Adventures Of Huckleberry Finn (1885). In 1880, Twain began promoting and financing the ill-fated Paige typesetter, an invention designed to make the printing process fully automatic. At the height of his naively optimistic involvement in the technological "wonder" that nearly drove him to bankruptcy, he published his satire, A Connecticut Yankee in King Arthur's Court (1889). Plagued by personal tragedy and financial failure, Mark Twain spent the last years of his life in gloom and exasperation, writing fables about "the damned human race."
