The American Academy of Arts and Sciences (AAA&S) is one of the oldest learned societies in the United States. It was founded in 1780 during the American Revolution by John Adams, John Hancock, James Bowdoin, Andrew Oliver, and other Founding Fathers of the United States. It is headquartered in Cambridge, Massachusetts.

John Hancock was an American Founding Father, merchant, statesman, and prominent Patriot of the American Revolution. He served as president of the Second Continental Congress and was the first and third governor of the Commonwealth of Massachusetts. He is remembered for his large and stylish signature on the United States Declaration of Independence, so much so that in the United States, John Hancock or Hancock has become a colloquialism for a person's signature. He also signed the Articles of Confederation, and used his influence to ensure that Massachusetts ratified the United States Constitution in 1788.
