Biography:

William Temple Franklin (London, 1760 – Paris, May 25, 1823) was a British-born American diplomat and real estate speculator. He is best known for his involvement with the American diplomatic mission in France during the American Revolutionary War. Beginning at the age of 16, he served as secretary to his grandfather Benjamin Franklin, who negotiated and agreed to the Franco-American Alliance.
The younger Franklin was also secretary for the American delegation that negotiated United States independence at the Treaty of Paris in 1783. He returned to Philadelphia with his grandfather afterward. Finding his prospects limited in the United States, he later returned to Europe, where he lived mostly in France.
