Edmond Frémy
Edmond Frémy , born with Versailles the February 28th 1814 and died in Paris the February 3rd 1894, is a Chimiste French.
He is initiated with chemistry by his father François Frémy, chemistry teacher with Saint-Cyr military school. In 1831, it enters to the laboratory of Gay-Lussac to the Polytechnic school and becomes its assistant in 1833. In 1837, it enters to the Collège de France and it is named preparer, then repeater, of Pelouze at the Polytechnic school, before succeeding to him as professor in 1846. In 1850, it succeeds Gay-Lussac with the pulpit of chemistry of the national Muséum of natural history, of which he is director of 1879 with 1891, following Eugene Chevreul. He is director of studies in the 2nd section of the practical École of the high studies. In 1857, it is elected member of the Academy of Science, of which he is president in 1875.
Frémy made research on the osmic acid, ferrates, stannates, plumbates and the Ozone. It tried to obtain free Fluor by molten electrolyzes of Fluorure S and discovered the hydrofluoric Acid Anhydre as well as a series of acids, whose precise nature was prone to discussion a long time. He studied the coloring of the sheets and the flowers, the composition of the bones and the brain, as well as other animal substances. He also studied the processes of Fermentation, subject on which he was in désacord with Pasteur.
Convinced of the importance of the technical applications of chemistry, Frémy is particularly interested as a professor in the training of the industrial chemists. In this field, it contributed to the studies on the manufacture of the Fer and the Acier S, the sulphuric Acid , the Verre and the Papier, and in particular worked on the Saponification of greases with sulphuric Acid and on the use of the Palmitic acid for the manufacture of the Bougie S.
In the last years of its life, it was concentrated on the problem of obtaining the Alumine in its crystalline form I, and succeeded in obtaining Rubis identical to the natural Gemme as well from the point of view of the chemical composition as of the physical properties.
