Presentation:

Famous and Not-So-Famous Unsolved Codes

Speaker(s):
Date & time (UTC/GMT):
October 17, 2020 5:00 PM
Description:

There are many famous codes and ciphers still waiting to be solved, such as the encrypted Voynich manuscript and the cryptic messages from the infamous Zodiac Killer. All hold a special fascination. In this talk, the International Conference on Cryptologic History will be entertained and informed by Elonka Dunin and Klaus Schmeh (who also have a new book coming out later in 2020, "Codebreaking: A Practical Guide"), as we briefly discuss the encryption on Kryptos, the mysterious sculpture at the center of CIA Headquarters; an encrypted engraving on an early 20th century silver cigarette case; the mysterious art in London's Cylob booklet; details about the message attached to the leg of a WWII carrier pigeon that was found a few years ago in an English chimney; messages showing up in bottles in the waterways of Hamburg, Germany; and the intriguing encrypted messages created by the mysterious Henry Debosnys while awaiting his murder trial in New York in the late 1800s.
