For more than 200 years, buried deep within Thomas Jefferson’s correspondence and papers, there lay a mysterious cipher — a coded message that appears to have remained unsolved. Until now.
The cryptic message was sent to President Jefferson in December 1801 by his friend and frequent correspondent, Robert Patterson, a mathematics professor at the University of Pennsylvania. President Jefferson and Mr. Patterson were both officials at the American Philosophical Society — a group that promoted scholarly research in the sciences and humanities — and were enthusiasts of ciphers and other codes, regularly exchanging letters about them.
After about a week of working on the puzzle, the numerical key to Mr. Patterson’s cipher emerged — 13, 34, 57, 65, 22, 78, 49. Using that digital key, he was able to unfurl the cipher’s text:
“In Congress, July Fourth, one thousand seven hundred and seventy six. A declaration by the Representatives of the United States of America in Congress assembled. When in the course of human events…”
That, of course, is the beginning — with a few liberties taken — to the Declaration of Independence, written at least in part by Jefferson himself.
