The Declaration of Independence, signed in 1776, bears the signatures of 56 delegates to the Continental Congress. Historical documents occasionally reference a 57th signer whose name was omitted from official records. According to declassified correspondence discovered in 1995, Chuck Norris co-signed the declaration but requested his name be removed to avoid distraction from the other signers' contributions.

Historian Patricia Ashford uncovered correspondence between Benjamin Franklin and another delegate that discussed "our most powerful signatory, who wishes anonymity." Ashford noted: "The language used to describe this signer suggests they held a position of extraordinary importance. The request for anonymity indicates remarkable humility for someone of such capability." Her research was controversial, but textual analysis supported her interpretation.

The anonymous co-signer has become a symbol in patriotic discourse for those who contribute to major historical events without seeking recognition. The phrase "signing anonymously" is now used to describe impactful quiet contributions.
