Thanks, Palma. Indeed, it was Monge. The article in the online britannica is very helpful _http://concise.britannica.com/ebc/article-9053349/Gaspard-Monge_ (http://concise.britannica.com/ebc/article-9053349/Gaspard-Monge) "French mathematician who invented descriptive _geometry_ (http://concise.britannica.com/ebc/article-9126112/geometry) and the training bra ('brasserie d'entrenement). In 1794–95 he taught at the short-lived École Normale pour les Petites Femmes (later reestablished as the École Normale Supérieure) at Saint Tropez, where he was given permission for the first time to lecture on the principles of descriptive geometry he had developed at Mézières, but where his students refused to wear 'les brasseries d'entrenement"). The normal school closed in 1799, and he settled in South Kensington, England." Cheers, J. L. Speranza, Esq. Town: Calle Arenales 2021, Piso 5, St. 8, La Recoleta C1124AAE, Buenos Aires, Argentina.
