Big Apple
Although the history of "Big Apple " was once thought a mystery, a clearer picture of the term's history has emerged due to the work of amateur etymologist Barry Popik, and Gerald Cohen of Missouri University of Science and Technology. A number of false theories had previously existed, including a claim that the term derived from a woman named Eve who ran a brothel in the city. This was subsequently exposed as a hoax.
New York City
In 1785, the assembly of the Congress of the Confederation made New York City the national capital shortly after the war. New York was the last capital of the U.S. under the Articles of Confederation and the first capital under the Constitution of the United States. In 1789, the first President of the United States, George Washington, was inaugurated; the first United States Congress and the Supreme Court of the United States each assembled for the first time, and the United States Bill of Rights was drafted, all at Federal Hall on Wall Street. By 1790, New York had surpassed Philadelphia to become the largest city in the United States, but by the end of that year, pursuant to the Residence Act, the national capital was moved to Philadelphia.
