The nation’s fourth president, James Madison (1751–1836) is perhaps best remembered as author of the Bill of Rights and one of the chief authors of the Federalist Papers. Educated at Princeton University, Madison served as a delegate to the Constitutional Convention and worked with Alexander Hamilton and John Jay to secure ratification of the Constitution. As a result, he produced a number of the Federalist Papers, seen as America’s great contribution to political philosophy and one of the seminal documents of the American founding period.
