Engineering Research Associates

Engineering Research Associates. It was a pioneering American computer company founded in 1946 by former personnel of the United States Navy's Communications Supplementary Activity - Washington (CSAW) and the Naval Computing Machine Laboratory. Established in St. Paul, Minnesota, the firm was instrumental in the early development of digital computers and cryptanalytic equipment, operating under secret contracts for the U.S. Navy and other government agencies. Its work formed a crucial bridge between wartime codebreaking efforts and the commercial computer industry.

History and founding

The company was incorporated in 1946 by a group led by William C. Norris, Howard Engstrom, and John L. Hill, all veterans of the U.S. Navy's wartime cryptologic efforts. These founders had worked at the Naval Computing Machine Laboratory in Washington, D.C., which developed advanced machines like the American Bombe to attack German Navy Enigma machine ciphers. With the end of World War II, they sought to continue their advanced engineering work in the private sector. With initial financing from John E. Parker of the St. Paul, Minnesota-based Northwest Aeronautical Corporation, they established their headquarters in a former Naval Air Station glider factory in St. Paul, Minnesota.

Major projects and contributions

The organization's early work focused on designing and building sophisticated electronic devices for cryptanalysis and data processing under contract to the U.S. Navy and the newly formed Armed Forces Security Agency. A landmark project was the Task 13 machine, a high-speed electronic cryptanalytic device completed in 1950. This was followed by the Atlas computer, also known as the ERA Atlas, delivered to the National Security Agency at Fort George G. Meade. These machines were among the first stored-program computers in the United States and were directly applied to signals intelligence tasks, advancing the state of the art in both computer architecture and cryptography.

ERA 1101 and early computers

A significant commercial and technical achievement was the development of the ERA 1101, one of the first commercially available scientific computers. The design was based on the earlier classified Atlas and was publicly unveiled in December 1950. The ERA 1101 utilized Williams tube cathode-ray tube memory and magnetic drum memory for storage. It was purchased by several government agencies, including the United States Air Force and the National Advisory Committee for Aeronautics, the predecessor to NASA. This machine established important precedents in computer programming and hardware design, influencing subsequent systems from other manufacturers like IBM and UNIVAC.

Relationship with the U.S. Navy

The relationship with the U.S. Navy was foundational and continuous. The company operated as a key private-sector partner for the Office of Naval Research and the Naval Security Group, performing highly classified research. Much of its funding came through the Cryptologic Research and Development program. This close alliance ensured a steady flow of challenging technical problems and funding but also meant that many of its most advanced innovations, such as the Atlas, remained state secrets for years. This dynamic positioned the firm at the forefront of applying digital electronics to national security challenges during the early Cold War.

Acquisition and legacy

In 1952, the company was acquired by Remington Rand, which was consolidating its position in the burgeoning computer market alongside its UNIVAC division. Under Remington Rand, the St. Paul, Minnesota operation became the core of its government computer engineering work. Following a series of corporate mergers, this lineage eventually became part of Sperry Corporation and later Unisys. The company's legacy is profound; its engineers, including William C. Norris and Seymour Cray, went on to found or lead major firms like Control Data Corporation and Cray Research, shaping the supercomputer industry. Its work established Minneapolis–Saint Paul as a major center for high-performance computing.
