the ideas of Bull, continued the improvement of the machine and the expansion of the company. Knutsen focused on new designs to record tabulation results on paper forms, sorted numerically and alphabetically. He was the first to use printing wheel methods. Groupe Bull The years following Bull's death, 1926, 1927 and 1928 were years of difficulty but also of joys and surprises. The machines installed and leased to Swiss companies had attracted great interest in Switzerland. In 1927, the Belgian Emile Genon bought the patents to operate in the European continent (excluding Scandinavia). In 1928 he got in agreement with the Swiss company HW Egli in order to produce Bull machines. Production began in 1929. Later Genon, aware of the improvements Knutsen was bringing in Scandinavia also tried to improve on his patents, the technology of the vertical sorting machine and printing. He finally hired Knutsen who was given the place of chief engineer of HW Egli. This was accepted by Knutsen with the condition of the company to moving to France where there was more to reach the market. So, in 1931 HW Egli - Bull based in Paris was founded. Two years later, in 1933, the company underwent a reorganization and suffered a name change, Compagnie des Machines Bull, the current Groupe Bull. Knutsen continued as chief engineer until his retirement in 1958.
