Who signed the Declaration of Independence first?

On August 2, 1776, the Congress members affixed their signatures to this parchment inside the Pennsylvania State House, later renamed Independence Hall. The first and largest signature was that of the president of Congress, John Hancock of Massachusetts. Not every man who had been present in Congress on July 4 signed the declaration on August 2. Historians believe seven of the 56 signatures on the document were placed there later.
