Anderson was a former slave who was freed from a Tennessee plantation by Union troops in 1864 and spent his remaining 40 years in Ohio. He lived quietly and likely would have been forgotten, if not for a remarkable letter to his former master published in a Cincinnati newspaper shortly after the Civil War.
Treasured as a social document, praised as a masterpiece of satire, Anderson's letter has been anthologized and published all over the world. Historians teach it, and the letter turns up occasionally on a blog or on Facebook. Humorist Andy Borowitz read the letter recently and called it, in an email to The Associated Press, "something Twain would have been proud to have written."
