John Dickinson.

John Dickinson was a delegate from Pennsylvania at the Second Continental Congress. Dickinson also served as the 5th President of Pennsylvania.

While John Dickinson's name is validly on the Constitution, he did not personally sign it. He authorized fellow delegate George Read to sign his name by proxy, as he was too ill to be there.

Interestingly, earlier in history, John had refused to sign the Declaration of Independence because he objected to violence in solving the challenges they faced.

John Dickinson is famous for being one of the founding fathers of the United States and for his role in drafting the Articles of Confederation. He also wrote the "Letters from a Farmer in Pennsylvania" which argued against British taxation before the American Revolution.

Ben Franklin was one of them. Hope this helps.
