Mark Twain Cave is actually the cave described in Mark Twain's book The Adventures of Tom Sawyer, or at least it influenced the cave descriptions very much. In the book Tom Sawyer and Becky Thatcher get lost in this maze of of corridors. And although the cave has spacious walk-ways and is rather dry and level, one can easily imagine how frightening it may be to get lost with no other light than candles.
Mark Twain is the pen name of Samuel Langhorne Clement (1835-1910). In the 1830s the Clemens family moved to Hannibal, Samuel Clement visited the cave many times as a boy. He describes several visits in his autobiography, tells that he scared his mother with bats he brought from the cave. He also tells that Injun Joe really existed.
The story of Injun Joe stealing dead bodies from the cemetery has several parallels to the real Dr. Joseph Nash McDowell. He bought the cave in the 1840s, locked it and made medical experiments and research on human corpses. From today's point of view, this is not so unusual for a surgeon, but at this time the people were disgusted. Especially as he was said to store the corpse of his 14 years old daughter in a glass flask in the cave, a commotion among the locals lead to the removing of the corpse.
During Civil War, Dr. McDowell stockpiled guns and ammunition for the Confederates at his medical college in St. Louis. So rumors of a munitions depot in his cave came up.
Then the cave description in the bestseller The Adventures of Tom Sawyer made the cave famous. The number of people visiting the cave increased continuously. In 1886 John East started a cave guide service. This makes the cave the first show cave of Missouri, and it has been open to the public continuously. The tours were made with lanterns until the cave got electric light in 1939.
