Which founding father served as the first Postmaster General?

Benjamin Franklin served as the first Postmaster General of the United States. Appointed in 1775 by the Continental Congress, Franklin was instrumental in establishing an efficient postal system, which was crucial for communication among the colonies and later, the states. His experience in managing postal services, both in the colonies and earlier with his own newspaper deliveries, made him a fitting choice for this position. By laying the groundwork for the postal system, Franklin contributed significantly to the nation’s infrastructure and helped promote connection and unity in the newly formed country.

The other figures listed—George Washington, John Hancock, and James Madison—had their own pivotal roles in American history, but they were not associated with the establishment of the Postal Service. Washington was the first President, Hancock is best known for his prominent signature on the Declaration of Independence, and Madison is often referred to as the "Father of the Constitution" for his key role in drafting it. Their contributions were vital to shaping the United States but do not pertain to the postal system specifically.
