Editing Gaspard Monge (section)

=== 1764-1818 ===
Those studying at the officer school were exclusively drawn from the aristocracy, so he was not allowed admission to the institution itself. His manual skill was highly regarded, but his mathematical skills were not made use of. Nevertheless, he worked on the development of his ideas in his spare time. At this time he came to contact with [[Charles Bossut]], the professor of mathematics at the École Royale du Génie. "I was a thousand times tempted," he said long afterwards, "to tear up my drawings in disgust at the esteem in which they were held, as if I had been good for nothing better."<ref name=EB1911/>

After a year at the École Royale, Monge was asked to produce a plan for a fortification in such a way as to optimise its defensive arrangement. There was an established method for doing this which involved lengthy calculations but Monge devised a way of solving the problems by using drawings. At first his solution was not accepted, since it had not taken the time judged to be necessary, but upon examination the value of the work was recognised,<ref name=EB1911/> and Monge's exceptional abilities were recognised.

After Bossut left the École Royale du Génie, Monge took his place in January 1769, and in 1770 he was also appointed instructor in experimental physics.<ref name="StA"/>

In 1777, Monge married Cathérine Huart, who owned a [[Forge|forge]]. This led Monge to develop an interest in [[metallurgy]]. In 1780 he became a member of the [[French Academy of Sciences]]; his friendship with chemist [[Claude Louis Berthollet|C. L. Berthollet]] began at this time.<ref name=EB1911/> In 1783, after leaving Mézières, he was, on the death of [[Étienne Bézout|É. Bézout]], appointed examiner of naval candidates.<ref name=EB1911/> Although pressed by the minister to prepare a complete course of mathematics, he declined to do so on the grounds that this would deprive Mme Bézout of her only income, that from the sale of the [[textbook]]s written by her late husband.<ref name=EB1911/> In 1786 he wrote and published his ''Traité élémentaire de la statique''.<ref name=EB1911/>
