Engineering Research Associates

Engineering Research Associates, commonly known as ERA, was a pioneering computer firm from the 1950s. They became famous for their numerical computers, but as the market expanded they became better known for their drum memory systems. They were eventually purchased by Remington Rand and merged into their UNIVAC department. Many of the company founders later left to form Control Data Corporation.

The ERA team started as a group of scientists and engineers working for the US Navy during WWII on code-breaking, a division known as the Communications Supplementary Activity - Washington (CSAW). After the war budgets were cut for most military projects, including CSAW. Joseph Wenger of the Navy's cryptoanalytic group was particularly worried that the CSAW team would spread to various companies and the Navy would lose their ability to quickly design new machines.

Wenger and two members of the CSAW team, William Norris and Howard Engstrom, started looking for investors interested in supporting the development of a new computer company. Their only real lead, at Kuhn, Loeb & Co., eventually fell through.

They then met John Parker, an investment banker who had run Northwest Aeronautical Corporation (NAC), a glider subsidiary of Chase Aircraft, in St. Paul, Minnesota. NAC was in the process of shutting down as the war ended most contracts, and Parker was looking for new projects to keep the factory running. He was told nothing about the work the team would do, but after being visited by a series of increasingly high ranking naval officers culminating with James Forrestal, he knew "something" was up and decided to give it a try. Norris, Engstrom, and their group incorporated ERA in January, 1946, hired forty of their codebreaking colleagues, and moved to the NAC factory.
