Mark Twain's River: Hannibal and the Truth About Tom Sawyer's World

Samuel Clemens was born in Florida, Missouri, in November of eighteen thirty-five, and moved to Hannibal on the Mississippi when he was four. He grew up there through the eighteen forties, in a river town where enslaved people were property and the river was both livelihood and spectacle. He left at seventeen to work as a printer's apprentice in St. Louis, and eventually became a licensed steamboat pilot on the Mississippi, working the river for four years before the Civil War closed navigation. He took his pen name from the pilot's depth call: mark twain meant two fathoms, safe water.

The Hannibal he wrote about in The Adventures of Tom Sawyer and Adventures of Huckleberry Finn was already a memory by the time he set the stories down in the eighteen seventies and eighties. The actual Hannibal of his childhood was a slave-state river town with an economy organized around the movement of cotton, hemp, and people south. Jim, the enslaved man at the center of Huckleberry Finn, is not an incidental character. He is the novel's moral core. The Mississippi carries both of them, Tom toward adventure and Jim toward whatever freedom the north bank might offer, on the same water that carried the commerce that made slavery profitable.

The museum in Hannibal is honest about both versions: the pastoral Twain of American mythology and the Twain who grew up watching auctions. The whitewashed fence is there. The fence is not the whole story.
