Life

Bertrand was a son of the mathematician Joseph Bertrand and nephew of the mathematician Charles Hermite . He studied at the École polytechnique (graduation in 1867) and from 1869 at the École des Mines in Paris. From 1873 to 1977 he was responsible for the minerals in the Vesoul area and the Luxeuil-les-Bains thermal baths , and from 1877 he was responsible for exploring the railway lines in eastern France. From 1878 he was involved in the geological mapping of France. In 1896 he was elected a member of the Académie des Sciences .

Bertrand was a representative of the doctrine of nappism. Through his investigations in the Alps and the South Belgian coal mountains near Namur in 1884, he made significant contributions to the development of the ceiling theory . The mineral bertrandite , which occurs in pegmatites and is used to extract beryllium, is named after him.

He was an officer of the Legion of Honor (1902), received the Prix Vaillant twice (1886, 1890), received the Prix Petit D'Ormoy in 1893 and was the first winner of the Prix Fontannes of the French Geological Society in 1888, of which he was Vice-President in 1886 and its President in 1891 .

Most recently (from around 1900) he was mentally deranged after the death of a daughter.
