The exhibit highlights the contributions of 24 women who have helped create cryptologic history. The display begins with a member of the Culper Spy Ring during the American Revolution who used her laundry as a secret code. Women spies from the Civil War also used codes and ciphers to aid those fighting for the causes they believed in. But it wasn't until the twentieth century that women began to work full-time in cryptology. During WWI, several women considered to cryptologic pioneers began their careers, as did some women few people today would know. During WWII, thousands of women joined the military or worked as civilians for the military as cryptanalysts, intercept operators, technicians, machinists and every other position available in cryptology. Many of those women chose to stay in the field after the war providing breakthroughs and contributions throughout the Cold War. Eventually, women rose to the highest ranks of management and today continue to support, develop, and build the cryptologic legacy of tomorrow.
