LOMBARD (Jean-Louis)

Scientist, mathematics professor and French military writer, born on August 23rd 1723, with Strasbourg, dead on April 1st 1794, with Auxonne. At eighteen years he was doctor of philosophy and with twenty, lawyer with the sovereign council of Alsace. After having spent four years in Paris, studying in turn mathematics and physics, the languages old and jurisprudence, it went to Metz in the intention to follow the career of the bar there; it was there that he knew Robillard, professor at the artillery schools, which gave him his/her daughter in marriage and at the same time the place that he occupied at the school of this city (1748).
La even year, it discovers the German translation made by Euler of the work of Benjamin Robins “ New artillery principles (News principles off gunnery) ” that it will translate into French. The translation of the work will be for him an incentive to carry out a checking of the principles by the experiment.
En 1759, it was called, during the creation of the Royal Artillery School of Auxonne, to teach there mathematics and the art of artillery.
C' is with the polygon of Tillenay, near to Auxonne, where proceed the firing practices, which it will make its experiments whose it will consign the results in a collection published in 1787, entitled “ Tables of the Shooting of the guns and the howitzers ” which will be still quoted in 1830.
En 1788, Lombard had Napoleon Bonaparte, then lieutenant with the regiment of Fère, as raises. Professor Lombard could appreciate the men, and one quotes as a proof of his sagacity the opinion that the pupil Napoleon Bonaparte, had inspired to him: “ this young man, said Lombard will go very far ”. And Bonaparte raises it recognized the school - without doubt thanks to the talents of Lombard- like “ the only one where the officers were capable to inform ”.
Cette eulogistic appreciation of Lombard was confirmed by Mortière, General inspector of Artillery, in the report/ratio which it draws up in 1789, and which said: “ I have just quoted at the moment the mathematics professor in charge of the theoretical instruction. He of it is little which as many has talents to lead young people to knowledge sublimes of mathematics, he does not limit himself to the public demonstrations of the rooms; he holds at his place conferences to which young people who want to acquire wider knowledge return and much can some profit. He often leads them on the terrein to make there the application of the principles of geometry to the lifting of the plans and the layouts of the fortifications of countryside ”.

With various Lombard recoveries had been charged by the governments with composing of the works which it could not, because them circumstances, to lead to end, inter alia a Cours with the use of the pupils of the artillery , undertaken in 1755 with Brakenhoffen ; another Course of Artillery , whose materials were yielded to Bezout, and a Traité Geometry , remained new.
