个人简介编辑本段回目录
Charles Xavier Thomas de Colmar (1785–1870) was a French inventor and entrepreneur best known for designing, patenting and manufacturing the first commercially successful mechanical calculator, the Arithmometer and for founding the insurance companies "Le Soleil" and "L'aigle" which, under his leadership, became the number one insurance group in France at the beginning of the Second Empire.
Charles Xavier Thomas的发明After a short employment in the French administration, he joined the French army in 1809 eventually reaching the level of General Manager of the supply store of all of the armies located in Spain in 1913. Shortly thereafter he was promoted to Inspector of Supply for the entire French army. It was during that time that he conceived the idea of the Arithmometer to help him with the great deal of calculations that he had to perform.
Back into civilian life, in 1819, he co-founded the fire insurance company "Phoenix" which he left quickly because of the lack of support for his new ideas from his partners and shareholders. Ten years later, in 1829, he started the fire insurance company "Le Soleil" that he grew by merger and acquisitions until his death. In 1843 he started another company insurance called "L'Aigle incendie". With the Sun (soleil) symbol of previous kings of France and the Eagle (aigle) reminiscent of Napoleon, he had all basis covered to attract a wide range of customers in a very divided 19th century France. By his death the "Aigle - Soleil" group was the biggest insurance business in France and he owned 81% of it!. Eighty years later, in 1946, it was nationalized and finally merged with "La National" in 1968 to become the GAN company which is still in business today.
Charles Xavier Thomas的发明Thomas was made Chevalier of the Legion d'Honor for his invention of the Arithmometer in 1821[1]. This is when he changed his name from "M. Charles Xavier Thomas" to "M. le Chevalier Thomas, de Colmar" and later simply "Thomas de Colmar". Again because of the Arithmometer, he was raised to the level of Officier of the Legion d'Honor in 1857.
Initially Thomas spent all of his time and energy on his insurance business, therefore there is a hiatus of more than thirty years in between the first model of the Arithmometer introduced in 1820 and its true commercialization in 1852. By the time of his death in 1870, his manufacturing facility had built around 1,000 Arithmometers, making it the first mass produced mechanical calculator in the world, and at the time, the only mechanical calculator reliable and dependable enough to be used in places like government agencies, banks, insurance companies and observatories just to name a few. The manufacturing of the Arithmometer went on for another 40 years until around 1914.
He married Francesca (Frasquita) Garcia de Ampudia Alvarez in Seville in 1812. She came from an old Andalusian noble family. Together, they had ten children from whom: Joseph Thomas d'Alvarez, Charlotte (countess de Rancy), Louis Thomas who married Livia Carafa, Duchess of Bojano and took the name of Thomas de Bojano, Frasquita (Mrs Soultzner) and Henriette (Countess de Dalmas).
主要贡献介绍编辑本段回目录
1785-1870
Charles Xavier Thomas de Colmar of France produced in1820 the first mass produced calculator for which he received the Chevalier of the Legion of Honor. De Colmar conceived of the project while serving in the army. The arithometer drew upon Leibniz's design through it use of stepped drum gears for calculation. De Colmar improved upon Leiniz's design by reversing the operating function in the result registers thereby prolonging use without gear re-alignment. Much like contemporary desktop computers, de Colmar's original arithometer occupied a whole desk and could not be moved by a single person. It spurred on many rivals, eventually leading to quite sophisticated calculating machines that overcame the pitfalls of the stepped-drum design. Thomas received France's for the product.
