James J. Gillogly is a PhD in Computer Science with a Ph.D. (Doctor of Philosophy) from Carnegie Mellon University (CMU) in 1978 . He worked at the prestigious RAND Corporation , a think tank that the United States Armed Forces advises. Jim, as he is called by his friends, is considered to be one of the leading cryptologists in the USA. For many decades he has been working successfully in the fields of computer science and cryptology . So he dealt intensively with the Beale ciphers and the Voynich manuscript . He became particularly famous for the cryptanalysis of the famous Kryptos riddle , the encrypted inscription on a sculpture by the American sculptor Jim Sanborn , which has been on the premises of the CIA headquarters in Langley , Virginia , since 1990 .

As early as 1970 he wrote in the programming language Fortran a chess program (see links ) and he has the first in 1977 adventure game in computer history, the Colossal Cave Adventure , Fortran into modern programming language C ported .

Jim was president of the American Cryptogram Association (ACA) and uses the pseudonym SCRYER. He is the editor of the cryptological journal Cryptologia . There he has also published many specialist articles himself, such as Ciphertext-Only Cryptanalysis of Enigma ( German  "Pure secret text attack on the Enigma" ), in which he describes an innovative method using Hill climbing to get Enigma - ciphertexts without the need for Cribs ( likely words) to break .
