1924: William Friedman receives first of 30 patents....

Friday, July 29, 2022

On 29 July 1924, William Friedman received a patent for a device to transmit telegraphic messages quickly, the first of his eventual 30 patents.

William Friedman, cryptologic pioneer, received a patent in 1924 for an “Apparatus for and Method of Rapid Transmission of Telegraphic Messages.” This invention improved the method of sending and receiving wireless communications “to simplify the work and increase the speed of such transmission of messages.” This was just the first of many inventions in which Friedman was involved. Some of his cryptologic inventions were so secret he couldn’t even apply for a patent. The classified nature of several others meant that he was not able to use his ideas for commercial design (or gain.) In 1956, the U.S. Congress awarded Mr. Friedman $100,000 as compensation.

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.
