Jacobs, like others who were involved in intelligence work during World War II, will probably never be adequately credited with his contributions to the field of computation and its usage in special problems. He was given several awards by branches of the US government for his service. Jacobs' wartime activities saw him spend a short period at Bletchley Park in England, although the major recorded activity of that period was his playing chess on board six in a challenge of the Oxford University chess club by the Bletchley Park regulars, including Jack Good and Hugh Alexander. Following the war, Jacobs took on a series of administrative positions at the US Department of Commerce, the US Air Force, and the National Security Agency. While with the Air Force, he installed their first Univac I, and pioneered the application of the computer to management problems. Later while at the National Security Agency he oversaw the development of software for the IBM-developed Harvest system, including the large-scale operating system, a high-level language, and an assembly-language system. After retiring from the NSA, Jacobs undertook an academic career at American University. With his brother, Morton Jacobs, Walter was instrumental in establishing the patentability of embedded software systems in 1975 before the US Supreme Court.
