Helen Fouché Gaines (1888–1940) was an American cryptographer best known for her book Cryptanalysis: A Study of Ciphers and Their Solution (1939). This work became a fundamental text in the field of classical cryptanalysis, providing techniques for solving different types of ciphers, including transposition and substitution ciphers. Her book remains a valuable resource for those studying historical cryptography methods. Gaines contributed significantly to the understanding and development of cipher-breaking techniques before modern computer-based cryptanalysis took over.
