亚历山大·居斯塔夫·艾菲尔（Alexandre Gustave Eiffel，1832年12月15日出生于法国第戎，1923年1月27日逝世于巴黎） 艾菲尔的祖先来自德国。他是一位法国工程师，金属结构专家，也是一位作家。 一开始他在巴黎综合理工学院求学，但没有毕业，接着转学到巴黎中央工艺制造学院（今巴黎中央理工学院），得到化学工程师的学位。

1856年他拿到了他第一个主要的工程委托，就是法国波尔多的加龙河铁道桥，他使用高压空气来驱动桥墩的技术是当时法国工程界的创举，这也是他终生最佳成就的表彰之一。

Alexandre Gustave Eiffel (born Bonickhausen dit Eiffel; /ˈaɪfəl/; French pronunciation: ​[efɛl]; 15 December 1832 – 27 December 1923) was a French civil engineer and architect. A graduate of the prestigious École Centrale des Arts et Manufactures of France, he made his name with various bridges for the French railway network, most famously the Garabit viaduct. He is best known for the world-famous Eiffel Tower, built for the 1889 Universal Exposition in Paris, and his contribution to building the Statue of Liberty in New York. After his retirement from engineering, Eiffel focused on research into meteorology and aerodynamics, making significant contributions in both fields.
