Which founding father was the oldest member of the Constitutional Convention?

The correct answer, Benjamin Franklin, was indeed the oldest member of the Constitutional Convention, which took place in Philadelphia in 1787. At the time of the Convention, Franklin was 81 years old. His extensive experience, both in diplomacy and in political affairs, was invaluable to the discussions that shaped the U.S. Constitution. Franklin's health had diminished by this time, but he still participated actively, contributing to compromises and promoting unity among the delegates.

George Washington, while an influential figure and later elected as the president of the Convention, was younger than Franklin. Thomas Jefferson was not present at the Convention, as he was serving as the American Minister to France. James Madison, often referred to as the "Father of the Constitution," was relatively young compared to Franklin, being in his mid-thirties. Given these details, Benjamin Franklin's age and contributions make him the correct answer in this context.
