Norwegian engineer
Fredrik Rosing Bull (1882–1925). After a reorganization in 1933, with new investors 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, Norwegian engineer
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 from 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 1993 the French Government initiated the process of privatization, which was completed in the period 1995-97 when the company was re-
privatised.
In August 2014, the French IT company
Atos announced that it had acquired a controlling stake in Bull SA through a tender offer launched in May. Atos announced plans in October, 2014 to buy out or squeeze out the remaining share and bondholders.
