Day Twelve – June 29, 2018 – Chautauqua
Day Twelve – June 29, 2018 – Chautauqua The first thing on today’s agenda is a lecture on codes; but it starts at nine!! Betsy, Roddy, and I are up early enough to have breakfast (delicious leftovers!) and Myra comes down, too, before we leave. We decide that the advantage of staying upstairs, in the “dormitory”, is that we get first dibs on breakfast! That done, we head to the United Methodist House for our lecture. Cool clock in the United Methodists house. The speaker, Chaz Kerschner, is a retired cryptanalysist from the NSA! He takes offense at my NPR shirt! Apparently there was a time when the NSA and NPR were enemies!! He’s being facetious (I think). His lecture is entitled, “”Codes – from Caesar to the 21 st Century” and begins with Egyptian hieroglyphics, moves on to the Rosetta Stone, Caesar’s Shift and all the other stages of code development, including the Enigma Machine, the Purple Code, Jefferson’s wheel cipher, and Navajo Code Ta
