American Cryptogram Association
The American Cryptogram Association (ACA) is an American non-profit organization devoted to the hobby of cryptography, with an emphasis on types of codes, ciphers, and cryptograms that can be solved either with pencil and paper, or with computers, but not computer-only systems. History The ACA was formed on September 1, 1930. Initially the primary interest was in monoalphabetic substitution ciphers (also known as "single alphabet" or "Aristocrat" puzzles), but this has since extended to dozens of different systems, such as Playfair, autokey, transposition, and Vigenère ciphers. Since some of its members had belonged to the “National Puzzlers' League”, some of the NPL terminology ("nom," "Krewe," etc.) is also used in the ACA.History ACA

Non-profit
A nonprofit organization (NPO) or non-profit organisation, also known as a non-business entity, not-for-profit organization, or nonprofit institution, is a legal entity organized and operated for a collective, public or social benefit, in contrast with an entity that operates as a business aiming to generate a profit for its owners. A nonprofit is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. An array of organizations are nonprofit, including some political organizations, schools, business associations, churches, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be tax-exempt, and some may also qualify to receive tax-deductible contributions, but an entity may incorporate as a nonprofit entity without securing tax-exempt status. Key aspects of nonprofits are accountability, trustworthiness, honesty, and openness to eve ...

Cryptography Organizations
Cryptography, or cryptology (from grc, , translit=kryptós "hidden, secret"; and ''graphein'', "to write", or ''-logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security ( data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymous with ...

James Gillogly
James J. Gillogly (born 5 March 1946) is an American computer scientist and cryptographer. Biography Early life His interest in cryptography stems from his boyhood, as did his interest in mathematics. By junior high he was inventing his own ciphers and challenging his father, entomologist Lorin Gillogly, to solve them. Gillogly wrote a chess-playing program in the Fortran programming language in 1970, and in 1977 he ported the code for " Colossal Cave" from Fortran to C. Education He graduated from Carnegie Mellon University in 1978, receiving a Ph.D. in computer science. He was advised by Allen Newell, with his dissertation titled "Performance Analysis of the Technology Chess Program". Career Gillogly worked as a computer scientist at RAND, specializing in system design and development, and computer security. He has written several articles about technology and cryptography, is currently the editor of the "Cipher Exchange" column for ''The Cryptogram'', and was president of t ...

Lexicographer
Lexicography is the study of lexicons, and is divided into two separate academic disciplines. It is the art of compiling dictionaries. * Practical lexicography is the art or craft of compiling, writing and editing dictionaries. * Theoretical lexicography is the scholarly study of semantic, orthographic, syntagmatic and paradigmatic features of lexemes of the lexicon (vocabulary) of a language, developing theories of dictionary components and structures linking the data in dictionaries, the needs for information by users in specific types of situations, and how users may best access the data incorporated in printed and electronic dictionaries. This is sometimes referred to as 'metalexicography'. There is some disagreement on the definition of lexicology, as distinct from lexicography. Some use "lexicology" as a synonym for theoretical lexicography; others use it to mean a branch of linguistics pertaining to the inventory of words in a particular language. A person de ...

Early life and education Will Shortz was born and raised on an Arabian horse farm in Crawfordsville, Indiana. He was drawn to puzzles at an early age; in eighth grade he wrote a paper titled “Puzzles as a Profession.” (The paper earned him a B+.) At age 13, Shortz wrote to ''Language on Vacation'' author Dmitri Borgmann for advice on how to pursue a career in puzzles. At age 16, Shortz began regularly contributing crossword puzzles to Dell publications. He eventually graduated from Indiana University in 1974, and is the only person known to hold a college degree in enigmatology, the study of puzzles.
