Abstract
Abstract During the second World War, American mathematician Paul Olum created two ciphers, labeled “Olum 1” and “Olum 2”, as challenges for the renowned atomic physicist Richard Feynman. These ciphers eluded solution by Feynman and remained unsolved for over 75 years. This manuscript presents the first successful decoding of the Olum 1 cipher. It describes the methods used to solve Olum 1 as well as the historical context of the once-classified information it contains. It concludes with observations about the possible authorship of additional ciphers given to Richard Feynman and examines the possibility that they, too, were created by Paul Olum.
期刊介绍：
Cryptologia is the only scholarly journal in the world dealing with the history, the technology, and the effect of the most important form of intelligence in the world today - communications intelligence. It fosters the study of all aspects of cryptology -- technical as well as historical and cultural. The journal"s articles have broken many new paths in intelligence history. They have told for the first time how a special agency prepared information from codebreaking for President Roosevelt, have described the ciphers of Lewis Carroll, revealed details of Hermann Goering"s wiretapping agency, published memoirs - written for it -- of some World War II American codebreakers, disclosed how American codebreaking affected the structure of the United Nations.
