1977: Lambros Callimahos Died.

Thursday, October 28, 2021

28 October 1977: Lambros Callimahos, noted NSA cryptanalyst and teacher, died. Mr. Callimahos was inducted into the NSA Cryptologic Hall of Honor in 2003. Read about his life and accomplishments via the link at the end of this page.

Excerpted from the NSA Cryptologic Hall of Honor record:

Through the 1950s, Mr. Callimahos collaborated with William Friedman on a variety of projects and developed his own famous class CA-400. This was an expansion of Friedman's original intensive-study senior cryptanalytic course. He taught 32 sessions of CA-400, for a total of 270 students. Graduates of CA-400, the elite among cryptanalysts, became members of the Dundee Society, a society made up by Mr. Callimahos named after the empty Dundee marmalade jar on his desk because he couldn't disclose the real purpose of the group, and played a crucial role in shaping cryptologic development at NSA.

A prolific writer of cryptologic literature, Mr. Callimahos was the author of over 40 books, monographs, and articles. He helped establish NSA's Technical Journal in 1955 and served as technical advisor to the publication for the rest of his career. He wrote articles on codes and ciphers for numerous reference works, including Encyclopedia Britannica.

By the end of his career, Mr. Callimahos was respected by his colleagues and students as a true Renaissance man: teacher, writer, linguist, cryptologist, and flutist. He was awarded the NSA Exceptional Civilian Service Award on 24 August 1976.

About Us

The NCF's Vision is to Influence the cryptologic future by sharing our educational resources, stimulating new knowledge, and commemorating our heritage.

The Foundation provides exceptional cryptologic programs throughout the year, encourages young minds to explore cryptology and cyber education and careers,  hosts educational, cryptology-related exhibits at various community events, and honors the people— past, present, and future—whose contributions to our national security protect and make possible our way of life.

The NCF also provides needed support to the National Cryptologic Museum (NCM), the first public museum in the U.S. Intelligence Community. Located adjacent to the National Security Agency (NSA) in Maryland, the NCM houses a unique and priceless collection of artifacts that represent our Nation's history in code making and code breaking, as well as a world class library of cryptologic media. The NCF acquires the best artifacts for the Museum and supports new educational and interactive exhibits.

As part of the Foundation's partnership with NSA to build the Cyber Center for Education and Innovation - Home of the National Cryptologic Museum (CCEI-NCM), the NCF also serves as a leader in the field of cybersecurity - striving to provide the best in educational resources and programs.

The NCF has a three-part mission to Educate, Stimulate, and Commemorate. Learn more about our MISSION.
