Brunsviga
Brunsviga was a calculating machine company whose history goes back to 1892. They produced mechanical calculators, hand operated but later also electrically driven. The firm Grimme, Natalis & Co that manufactured the machines changed their name to Brunsviga Maschinenwerke A.G. in 1927. Origins The Brusviga device had its roots in the arithmometer developed by Willgodt Theophil Odhner (1845–1905), (de) Brunsviga-Gesichte 1892-1912 : 20 Jahre Rechenmaschinenfabrikation. 20 000 Brunsviga Rechenmaschinen verkauft 20000, Braunschweig, 1912., Moos am Bodensee, Verlag Greis, 2020, 36 p. (ISBN 978-3-941937-36-9) a Swedish engineer who emigrated to Russia for work purposes in 1868 or 1869 after having studied mechanics at the Royal Institute of Technology in Stockholm. Odhner was hired by his fellow Swede Ludvig Nobel (Albert Nobel's brother) who was the head of an arms factory. His job there was to fix the so-called Thomas Arithmometers, named after their designer in the 1820s. The t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympia-Werke
Olympia-Werke AG was an important German manufacturer of typewriters and other office equipment. Since the plant in near Wilhelmshaven was closed in 1991, only the brand name has survived. Beginnings (1903–1945) As typewriters became increasingly popular in Germany in the early 20th century, the Allgemeine Elektricitäts-Gesellschaft (AEG) in Berlin commissioned Friedrich von Hefner-Alteneck, an electrical engineer, to develop such a device. Hefner-Alteneck then designed the Mignon, an inexpensive pointer typewriter that was not only affordable for larger companies, but also for craftsmen and private individuals. On 15 August 1903, Olympia-Werke was founded as the ''Union Schreibmaschinen-Gesellschaft m.b.H.'' to sell the Mignon. Beginning in 1930, the company traded as Europa Schreibmaschinen AG ( Europa Typewriters AG); internationally, the products were sold under the trademark ''Olympia''. The last "Mignon" from 1933 was called the Olympia-Plurotyp. On 31 December 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arithmometer
The arithmometer () was the first digital data, digital mechanical calculator strong and reliable enough to be used daily in an office environment. This calculator could add and subtract two numbers directly and perform Multiplication algorithm, long multiplications and divisions effectively by using a movable accumulator for the result. Patented in France by Charles_Xavier_Thomas, Thomas de Colmar in 1820 and manufactured from 1851 to 1915, it became the first commercially successful mechanical calculator.Chase G.C.: ''History of Mechanical Computing Machinery'', Vol. 2, Number 3, July 1980, page 204, IEEE Annals of the History of Computing https://archive.org/details/ChaseMechanicalComputingMachinery Its sturdy design gave it a strong reputation for reliability and accuracy and made it a key player in the move from to calculating machines that took place during the second half of the 19th century. Its production debut of 1851 launched the mechanical calculator industry which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fritz Müller-Partenkirchen
Fritz Müller-Partenkirchen (born ''Friedrich Müller''; 24 February 1875 in Munich; 4 February 1942 in Hundham) was a German writer. From 1892 to 1895, he studied merchant trade and became an accountant, later a teacher of commerce in Partenkirchen. Around the age of 38, he studied law and economics at the University of Zurich. He attended a lecture by Albert Einstein in 1911 on the theory of relativity, of which he gave a popular report in the newspaper Berliner Tageblatt in 1911.; A partial English translation of some sections from Müller's paper can be found on pp. 300ff. in ''Gilbert, L. (1914)A satire on the principle of relativity The Monist, 288-309.''; See also Das Zeitproblem on German Wikisource Müller's report on relativity was described by Könneker (2001). In 1915, a first edition of the World War I stories and experiences was published. In the 1920s, he adopted the artistic name Müller-Partenkirchen and wrote, often in a humorous style, merchant stories and nov ...

Karl Pearson
Karl Pearson (; born Carl Pearson; 27 March 1857 – 27 April 1936) was an English biostatistician and mathematician. He has been credited with establishing the discipline of mathematical statistics. He founded the world's first university statistics department at University College London in 1911, and contributed significantly to the field of biometrics and meteorology. Pearson was also a proponent of Social Darwinism and eugenics, and his thought is an example of what is today described as scientific racism. Pearson was a protégé and biographer of Sir Francis Galton. He edited and completed both William Kingdon Clifford's ''Common Sense of the Exact Sciences'' (1885) and Isaac Todhunter's ''History of the Theory of Elasticity'', Vol. 1 (1886–1893) and Vol. 2 (1893), following their deaths.
