John Dickinson burst onto the scene with his "Letters from a Farmer in Pennsylvania" published in a Philadelphia newspaper in 1767 and 1768. He wrote "The Liberty Song," sung all over America, including at the 1769 Sons of Liberty dinner in Dorchester, Massachusetts, and the Continental Congress's Olive Branch Petition and with Jefferson the "Declaration on the Causes and Necessity of Taking Up Arms." While he opposed the Declaration of Independence, he drafted the Articles of Confederation, and in 1787 was a member of the Constitutional Convention. We talk about Dickinson with Dr. Jane Calvert, author of the new biography, Penman of the Founding: A Biography of John Dickinson , and the Director and Chief Editor of the John Dickinson Writings Project.
