His son, who would become one of the wealthiest authors in America, would follow in his father’s financially-shaky footsteps as an adult and was prone to speculation and ill-advised investments that would repeatedly threaten his financial security. John also dabbled in land speculation, leaving the family’s finances often precarious. When Twain was 4 years old, his family moved to the Mississippi River port town of Hannibal, where John worked as a lawyer, storekeeper and judge.

He was a sickly youth, whose parents feared he might not survive, and the family was beset by the tragic early deaths of three of Twain’s siblings. He was the sixth of seven children born to John and Jane Clemens. Samuel Langhorne Clemens was born in the tiny town of Florida, Missouri, on November 30, 1835, two weeks after Halley’s Comet made its closest approach to the Earth. The childhood years spent in this Missouri town gave birth to some of the most famous characters in American literature, an emotional and memory-filled well that Twain would return to again and again.

Few American authors are as closely intertwined - and influenced - by their hometowns as Twain. Hannibal, Missouri made Mark Twain, and, in turn, Twain made Hannibal famous.
