Who was the first unofficial postmaster general of the United States?

Benjamin Franklin was the first unofficial postmaster general of the United States, a role he assumed during the colonial period. Appointed in 1753 as the postmaster of Philadelphia, he revolutionized the postal service by improving its efficiency and expanding its network. Under his leadership, the postal service began to function more effectively, with regular schedules and better communication between the colonies.

Franklin's contributions extended beyond just managing the postal service; he also established a system of post roads and advocated for lower mailing rates, which made it easier for the colonies to communicate with one another. By the time of the American Revolution, Franklin's work laid the groundwork for a more organized postal system, eventually leading to the establishment of the United States Postal Service.

The other individuals listed, while prominent figures in American history, did not hold a position specifically recognized as postmaster general under the same context. This makes Franklin's role distinctive as he is often credited with shaping the foundations of the post office that served the early United States.
