Just got back from a weekend writer's conference, and learned a bit of interesting historical trivial from the keynote speaker. Did you all know that the bestselling book in the 19th Century was Uylsses S. Grant's memoirs?
He explained that Grant had to give up his army pension when he ran for President, and that later in life he became impoverished. In order to secure that his widow wouldn't become destitute after his death he wrote his memoirs. They are still in print today. You can even find them on Amazon.com and download them to a Kindle. Wonder what Grant would have thought about e-books?
