"Lord" Timothy Dexter of Massachusetts published his autobiographical A Pickle for the Knowing Ones; or Plain Truths in a Homespun Dress (presented here with "translation") in 1802.
He wrote about himself and complained about politicians, clergy and his wife. The book contained 8,847 words and 33,864 letters, but absolutely no punctuation, and capital letters were sprinkled about at random.
When people complained that it was hard to read, for the second edition he added an extra page - of punctuation marks - asking readers to "peper and solt it as thay plese". [Link]
