James Madison
James Madison, Jr. (March 16, 1751 – June 28, 1836) was the fourth President of the United States and is also known as the Father of the Constitution for his role in drafting and helping to ratify the Constitution, with his wife Dolley Madison. Madison was born in Virginia into a family of tobacco plantation owners, and was diligent about his studies despite his frail physicality. After graduating from Princeton in 1771, Madison became interested in the declining relationship between Great Britain and the colonies, and joined a pro-revolutionary group despite not being able to serve in combat because of his physical condition.
During the Revolutionary War, Madison became a prominent figure in political matters while serving in the Virginia legislature. Later, he drafted the Constitution, and in order to ratify it, he wrote some of the Federalist Papers. His role regarding the Constitution is considered very important to the actual ratification. After the establishment of the new government, Madison strove to be elected into Congress, and was barely able to make it. However, once he entered, he became an important figure and established many amendments to the Constitution, including the Bill of Rights.
Later, Madison returned with Dolley to the Montpelier estate that was inherited from his father to retire and died at the age of 85.
