Reading Walter Isaacson’s biography was insightful into one of the most famous Founding Fathers, but one who is probably lesser known for his intellect. Isaacson brings the human being to the forefront of this almost mythical figure. Franklin was the only Founding Father to sign all four major American Revolution documents; the Declaration of Independence, Treaty with France, Peace Accord with Great Britain, and the United States Constitution. In later life he was President of the Pennsylvania Society for Promoting the Abolition of Slavery.
