巴黎综合理工学院(Ecole Polytechnique,以下简称EP)诞生于法国大革命的电闪雷鸣之中:当时外敌压境、内争纷起、叛乱频仍,共和国的道路桥梁遭到严重的破坏,为了迅速调遣军队保卫祖国,国民公会接受学者们的建议,决定以最快的速度在巴黎兴办一所培养道桥技术人才和工兵及炮兵军官的学校.发起建议的科学家包括时任国民公会主席的数学家老卡诺(Lazare Carnot,1753-1823)、画法几何的奠基人蒙日(Gaspard Menge,1746-1818)、化学家贝托莱(Claude-Louis Berthollet,1748-1822)、天文学家拉普拉斯(Pierre Simon de Laplace,1749-1827)等.国民公会于1794年3月11日通过建校法案,12月正式开课,校址设在塞纳河边的波旁宫,学生多为贫家子弟,分散居住到附近的公民家庭而由国家给予补贴.
