Rare Book Collection
The Museum's rare book collection includes books believed to have been acquired during the 1930s by the small group of individuals who worked for William Friedman. The books are not codebooks but are texts that elaborate on the science of cryptography. The collection includes an extremely rare copy of the first book ever written in the Western world on the subject of cryptology, Polygraphiae by Johannes Trithemius, published in 1518. Other books in the Museum collection date back to the 16th century as well and many include notes made in the margins by the students using them in the 20th century.
