Who was the man that signed all 4 documents?

The man who signed all four foundational documents of the United States—namely the Declaration of Independence, the Articles of Confederation, the U.S. Constitution, and the Bill of Rights—was George Washington. However, it’s important to note that while Washington is famously associated with these documents, he did not sign the Declaration of Independence or the Bill of Rights. Instead, Thomas Jefferson, John Adams, Benjamin Franklin, and others signed the Declaration, while Washington presided over the Constitutional Convention and his signature is on the Constitution itself.
