Charles Combes

Charles Pierre Mathieu Combes (26 December 1801 – 11 January 1872) was a French engineer. He was Inspector-General of Mines and the Director of the School of Mines in Paris. His name is on the Eiffel Tower.

Charles-Pierre-Mathieu Combes was born on 26 December 1801 in Cahors. His father was a senior policeman named Pierre Combes Mathieu. He joined the Ecole Polytechnique before the usual starting age of seventeen on 1 September 1817 and completed his studies in 1820 when he was admitted to the School of Mines. Combes completed the three-year course in just two years. He graduated on 1 July 1822.

In 1825 he became a teacher of mathematics at the Ecole de Saint-Etienne, a post he held for two years. He then worked in industry but returned to the Saint-Etienne school in 1827 and stayed until 1831.

In 1832 he started at the School of Mines in Paris.

Combes' wife Louise Pauline (born Bousquet) died young in 1841.

As the manager of the Firminy colliery, Combes took a special interest in the question of underground mine ventilation at which he became an expert and which, according to A. de Lapparent,

was to keep him busy for the rest of his career.

Combes took an interest in his students. A young Marcel Deprez failed to complete the course at the School of Mines. He must have made a good impression as he was employed as Combes' secretary. Deprez went on to show that electricity could be transmitted over long distances.
