What is Benjamin Franklin known for?

Benjamin Franklin is known for his significant contributions as a U.S. diplomat, particularly during the American Revolution. He played a crucial role in securing essential support from France, which was pivotal for the success of the American colonies in their fight for independence. Franklin's diplomatic efforts included negotiating the Treaty of Paris in 1783, which officially ended the war and recognized American independence.

His skill in diplomacy was complemented by his broad knowledge and experience, making him a respected figure both in the United States and abroad. While he contributed to many areas of civic life, such as science and philosophy, his diplomatic achievements stand out prominently in American history.
