Life and work

Edmond Frémy received his first lessons from his father François chemical Frémy (Professor of Chemistry at the Military School of Saint- Cyr ), 1833 was assistant to Louis Joseph Gay -Lussac, 1837 at Théophile -Jules Pelouze 1842 and associate professor at the Muséum national d' histoire naturelle. In 1845 he discovered potassium nitrosodisulfonate, which is named after him Fremys salt.

Fremy was married since 1840 to Eugénie Félicité Germaine Boutron (* 1820 ) was her son Edouard, Comte Frémy ( 1843-1904 ).

In 1846 he became a professor at the École polytechnique and since 1850 at the Natural History Museum as a successor of Gay-Lussac. From 1879 to 1891 he was the successor of Michel Eugène Chevreul, director of the museum. In 1857 he was elected to the Académie des sciences.

In 1864 he founded the first laboratory in France ( the Natural Science Museum ), which was devoted exclusively to the study and scientific investigations, in which students were trained without tuition.

Frémy delivered uncommonly numerous investigations, he discovered the Metaantimonsäure, the ammonia cobalt compounds and a method for the preparation of artificial gems, and also the palmitic acid and oleic it. He worked on tartaric acid, lactic acid, Pektinkörper, cellulose, chlorophyll, on the composition of bone, protein and muscles.

When he was elected following the death Pelouzes in managing the large glass factory of Saint- Gobain ( Compagnie de Saint- Gobain ), he made attempts to prepare sulfuric acid from gypsum, by air and an investigation of the functions of Gay on the decomposition of hydrochloric acid Lussac tower in the manufacture of sulfuric acid; notably, it also discovered the saponification of fats with sulfuric acid for the Stearinkerzenfabrikation.

Andre works refer to the glass industry, the production of artificial fertilizers, on the cement, iron and steel industry, and the employment of plant fibrous textile and paper manufacturing. With Pelouze he published several textbooks of chemistry; also he was in the club with professional colleagues published a " Encyclopédie Chimique ".
