Bull SAS (also known as Groupe Bull, Bull Information Systems, or simply Bull) is a French computer company headquartered in Les Clayes-sous-Bois, in the western suburbs of Paris. The company has also been known at various times as Bull General Electric, Honeywell Bull, CII Honeywell Bull, and Bull HN. Bull was founded in 1931, as H.W. Egli - Bull, to capitalize on the punched card technology patents of Norwegian engineer Fredrik Rosing Bull (1882–1925). After a reorganization in 1933, with new owners coming in, the name was changed to Compagnie des Machines Bull (CMB). Bull has a worldwide presence in more than 100 countries and is particularly active in the defense, finance, health care, manufacturing, public, and telecommunication sectors. History Origins On 31 July 1919, a Norwegian engineer named Fredrik Rosing Bull filed a patent for a "combined sorter-recorder-tabulator of punch cards" machine that he had developed with financing from the Norwegian insurance company Storebrand. Storebrand integrated his device into its operations in 1921. The following year Bull sold his second machine to the Danish insurer Hafnia who had learned of the technology through an article in an insurance trade magazine. At the time of Bull's death of cancer in 1925 at the age of 43, a dozen of his machines had been sold to different companies throughout Europe. The commercial and technical development of the machines continued under the direction of Bull's childhood friend and long-time collaborator Reidar Knutsen along with his brother Kurt Andréas Knutsen. As the business grew several outside investors were brought in, leading to the incorporation of the company H.W. Egli Bull in 1931. In 1933, more investors joined and the company changed its name to Compagnie des Machines Bull, a name it would keep until 1964. Growth The company has undergone many takeovers and mergers since its formation. In particular, it has had various ownership relations with General Electric, Honeywell, and NEC from the 1960s to the 1980s; and with Motorola, Debeka, and France Télécom more recently. It acquired Honeywell Information Systems in the late 1980s, and later also had a share of Zenith Data Systems and Packard Bell. Bull was nationalised in 1982 and was merged with most of the rest of the French computer industry. Groupe Bull bought Zenith Electronics in late December 1989. It kept Zenith Data Systems' headquarters and plants in Chicago and St. Joseph, Michigan. In 1994, the company
