The mission of the Fédération des Équipes Bull is to safeguard and promote the historical and cultural heritage of Bull and French IT.
From early computing milestones to today’s digital solutions, our story is shaped by scientific expertise and industrial progress that continue to guide how we innovate and deliver value.
The Bull Teams Federation (Fédération des Equipes Bull) is an association under the French Law of 1901 founded in 1986. It stems from a gathering of passionate men and women, some of them clients or partners, most of them former Bull employees, who have devoted a great effort over the years to safeguarding and promoting the historical and cultural heritage of the Bull.
Our teams rely on the skills of FEB members to preserve and enrich the Group’s collections and archives, and more generally those of French IT, while making them accessible to historians, researchers and students.
The collection of hardware designed and marketed by Bull or by competitors is currently divided between the Angers industrial site and the Clayes-sous-Bois campus in France, while a subset of the collection dedicated to printing systems is on display in Belfort. FEB Belgium has donated its archives to the Computer Museum NAM-IP in Namur. Some important equipment developed by Bull is also on display or stored in the reserves of other French institutions, such as the “Musée des Arts et Métiers”, the “Cité des Sciences et de l’Industrie” and the “Association pour un Conservatoire de l’Informatique et de la Télématique” (ACONIT). All French machines are listed in an inventory managed by FEB.
Bull’s friends continue to gather to retrace this human, technological and economic adventure.

The mission of the Fédération des Équipes Bull is to safeguard and promote the historical and cultural heritage of Bull and French IT.
To exploit the statistical machine patents filed by the Norwegian engineer Fredrik Rosing Bull (1882-1925) in the 1920s, “H.W. Egli-Bull”, a subsidiary of Swiss company H.W. EGLI, was founded in 1931 in France, offering a larger potential market than in Switzerland.
Based in central Paris, the company specialised in the manufacture of tabulators, punch card sorters and punching machines. These machines were constantly being improved, to the great satisfaction of their users. The T30 tabulator was the first machine to leave Paris’ workshops. It was equipped with an innovative printing device based on a wheel system, allowing numeric and alphanumeric characters to be printed at a higher speed than its competitors. Bull’s pioneering spirit, the innovative nature of its activities, and the financial backing of the French “Syndicat des Utilisants” and later the Calliès-Aussedat family all contributed to the company’s success against its main competitors: IBM and Remington Rand.
