On this day in 1775, the U.S. postal system is established by the Second Continental Congress, with Benjamin Franklin as its first postmaster general. Franklin (1706-1790) put in place the foundation for many aspects of today’s mail system. During early colonial times in the 1600s, few American colonists needed to send mail to each other; it was more likely that their correspondence was with letter writers in Britain. Mail deliveries from across the Atlantic were sporadic and could take many months to arrive. There were no post offices in the colonies, so mail was typically left at inns and taverns. In 1753, Benjamin Franklin, who had been postmaster of Philadelphia, became one of two joint postmasters general for the colonies.
