Who was the founding father who signed the Declaration of Independence?

In 1776, 25 years before he became President, Thomas Jefferson was the primary author of the Declaration of Independence, which severed the ties of the colonies with Great Britain.

Jefferson was the one responsible for writing both the first and final draft. However, he was actually part of a committee appointed by the Second Continental Congress to write it. The other four members were Benjamin Franklin, John Adams, Robert R. Livingston and Roger Sherman, all of whom provided recommendations on the language of the document.
