Signature

Bull was born in Kristiania (Oslo, Norway). In 1907 he finished his studies in civil engineering at the Technical School of Kristiania (Kristiania Tekniske Skole).[1] In 1916 he was hired as a technical inspector for the insurance company Storebrand, where he developed an interest for punched card machines technology and began developing one of his own. In 1919 he obtained a patent for the machine, and in 1921 he prepared a team that took over the implementation of the machine at the company where Bull worked at that time, Storebrand. This team provided several new ideas for improving the Bull machine, rendering it superior to Hollerith's device - the precursor to the IBM punched card machine - in use at that time. Bull continued to develop his ideas, improving the machine, which became a success throughout Europe. He was diagnosed with cancer at an early age and died in 1925 when he was 42 years old. His patents were later sold in 1931 and constituted the basis for the founding of the French company Groupe Bull, a large information technology company operating in over 100 countries.

Family

Fredrik Bull was born in Kristiania (the present-day Oslo) to Dr. Ole Bornemann Bull (1842–1916) and his first wife Marie Cathrine Lund (1843–1884).[2] Dr. Ole Bull was a renowned eye doctor. He collaborated with Gerhard Armauer Hansen who discovered Mycobacterium leprae, the causative agent of leprosy, while investigating the effects of leprosy on the eyes. He is also known for having developed a method to determine the degree of sensation of color.

Fredrik was raised in a large family. He was the eighth of fifteen children. The Bull family had a passion for technology and science: all of Fredrik's older brothers were engineers. His brother Anders Henrik Bull is known for his studies in wireless radiotelegraphy.

Education

Fredrik Rosing Bull began his studies in civil engineering at the reputable Technical School of Kristiania in 1904 and graduated in 1907.[1] He scored some of the best marks of class.

Storebrand

In 1916 he was hired as a technical inspector at the insurance company Storebrand where he came into contact with the tabulating machines of those days.[1]

The punched cards and the tabulating machines were initially developed by the U.S. engineer Herman Hollerith and were used for first time in Norway by Statistics Norway in 1894.

Fredrik Bull was sent abroad to study Hollerith's systems, returning with the conviction that Hollerith's systems were expensive and unstable. He was convinced that he could develop a device that was cheaper and more efficient than Hollerith's. As a result, Bull convinced his employer, Storebrand, to pay him an advance of $10,000 to develop a new machine. The terms of the deal required the advance to be repaid in full if the machine was not successful.

Bull's plan was to use electromagnetic technology like Hollerith, but with a considerable number of improvements. The use of 45 column punched cards enabled the machine to read the information while making contact through the holes. This method allowed faster processing of the information. The existing machines in use at that time required significant manual intervention to operate. Bull made several improvements to automate processing such as standardization of punched-cards and pre-selection.

Bull's first machine

Bull needed almost 2 years to turn his ideas into a finished product. The machine was presented to the Storebrand directors at his workshop on 12 January 1921 and subsequently purchased for the sum of 20,000 pounds on 21 January 1921. The machine was not a success because it was not as efficient, stable and reliable as expected. However, it was in operation until 1926.[1]

Around the same time Bull contacted an old friend named Reidar Knutsen from high school in Nordstrand, who headed the company A/S Oka. Through Reidar he met Knut Andreas Knutsen, Reidar's younger brother, who was an engineer, and he and Bull began collaborating.

The Bull machine

On 31 July 1919 Bull obtained a patent for his design. The patent describes in detail his idea of a programmable tabulating machine. The new machine itself was not completed until 1923 and was referred to as a 'ordering, recording and adding machine'. After its initial success Bull undertook the production of new copies of his T-30 machine, adding improvements as he went. Several insurance companies in Denmark showed interest in the technology.

Fredrik then signed a contract the Oka company led by Reidar Knutsen, which assumed the costs of manufacturing and marketing. The production of these machines was in a precision workshop in Kristiania.[1]

The Bull machine used punched card of 45 columns, with round holes and a rotating adder. His machine was substantially better than its competition, Hollerith and Powers, through the mechanism of punched card pre-selection.

The machine proved a success and received very good reviews and publicity The key factors for success were the technical quality of the machine, the ease of use, the new pre-selection technology, the cost savings and the opportunity for users to avoid IBM's monopoly and purchase their own equipment instead of renting it.

Other patents

Bull continued working on improvements for the machine and also in developing new machines such as a sorting machine and a new tabulating machine.

Some of the notable improvements were: the change of switches that controlled the entry of punched cards and the expansion device in larger scale.

The reading device was the most critical part of the machine. Built with electrical conductors or springs, punched cards were introduced, the springs passed through the holes producing contact. The springs only passed through the holes of the punched cards, causing the information to be recorded. He obtained the ideas for this machine by stealing the notes of Henrik Hartzner, his Danish partner. One of the main problems of this method was the low durability of the material of the cards, which meant that the method did not always work the right way. Another major problem was the dust that entered the holes of the contacts. Finally, one of the biggest problems Bull and Knutsen had to face was that because of the contacts, sparks were created causing the machine to crash frequently. All these details were being constantly improved.

Production of Bull machines was rather slow. In 1921 there was a production of 2 machines, 2 in 1922, 2 in 1923, 4 to 1924 and 6 in 1925, distributed among companies in Norway, Denmark (Hafnia as a notable client), Finland and Switzerland. There were constant problems with the machines; Knut Andreas Knutsen was continuously traveling to these countries for repair and modifications at client sites.[1]

Illness and death

In the summer of 1924 Bull was diagnosed with cancer, a disease that ended his life on 7 June 1925 when Bull was only 42 years old.

Despite the diagnosis in the summer of 1924, Bull continued to work until his condition worsened in the fall of that year. In the last few days he shared his latest ideas with Knutsen. Bull's patent rights were acquired by Oka, where Knutsen, loyal to 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.[1]

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[3]. Knutsen continued as chief engineer until his retirement in 1958.

gollark: Production and shipping have stopped because coronavirus.
gollark: Sadly there aren't more available right now.
gollark: And yes, I do want a pinephone.
gollark: Yes.
