James Madison is known as the Father of the Constitution. Before the Constitutional Convention, Madison spent many hours studying government structures from around the world before coming up with the basic idea of a blended republic. While he did not personally write every part of the Constitution, he was a key player in all discussions and forcefully argued for many items that would eventually make it into the Constitution including population-based representation in Congress, the need for checks and balances, and support for a strong federal executive.
