Are you sure about that?
Taken from the book description of "Gentleman Revolutionary: Gouverneur Morris, the Rake Who Wrote the Constitution."
James Madison admitted it after Gouverneur Morris died: Madison held the title "Father of the Constitution," but the "finish given to the style and arrangement of the Constitution fairly belongs to the pen of Mr. Morris." The author of the great Preamble to the Constitution and much of the rest of the document was a wealthy, raffish New Yorker who was above all things a loyal son of the American Revolution.
It advanced, persuasively, that the document the "Committee on Stile" used as the text from which to draft the Constitution had been submitted by Charles Pinckney of South Carolina. That original document was missing from the papers of the Convention, kept very sloppily by Major Jackson, its original Secretary.
As for the Amendments, James Madison, a Member of the House in the First Congress, was tasked with distilling the 200+ demands for items in a Bill of Rights into a specific set of amendments. He drafted 17 amendments, which passed the House. The Senate then reduced those to 12 Amendments, which were sent out for ratification.
Of those twelve, the third through twelfth were quickly ratified, and became the Bill of Rights. What was the Third Amendment as submitted, became the First Amendment as ratified. The original Second Amendment, concerning congressional pay raises, did not get ratified until 1992, as the Twenty-Seventh Amendment. The original First Amendment was defeated.
I have all this history in one of my books. I wrote the Introduction to the facsimile reprint of Robert Yates' Secret Procedings and Debates of the Convention to Form the US Constitution. Trust me, I know these things.
