Riverbank Publications
Pamphlets written by workers of George Fabyan / From Wikipedia, the free encyclopedia
The Riverbank Publications is a series of pamphlets written by the people who worked for millionaire George Fabyan in the multi-discipline research facility he built in the early 20th century near Chicago. They were published by Fabyan, often without author credit. The publications on cryptanalysis,[1] mostly written by William Friedman, with contributions from Elizebeth Smith Friedman and others, are considered seminal in the field.[2] In particular, Publication 22 introduced the Index of Coincidence, a powerful statistical tool for cryptanalysis.
