James Madison — Constitution Architect, Father of the Bill of Rights

**James Madison** was the principal architect of the United States Constitution — the document that has governed the world's oldest continuous republic for over 230 years. Standing 5'4" and rarely exceeding 100 pounds, he was the smallest of the founders and the quietest in a room. But Madison's mind was the most systematic and rigorous of the entire generation. While others brought passion, rhetoric, or military glory, Madison brought the thing that actually made the American experiment work: a detailed understanding of how governments fail, and a structural design to prevent it.
