Auguste Verneuil
Auguste Victor Louis Verneuil (born November 3, 1856 in Dunkerque , Département Nord , † April 27, 1913 ) was a French chemist who became known for inventing a commercial process for the production of synthetic gemstones . In 1902 he invented the flame fusion process, which is known today as the Verneuil process . The process is still used today for the production of corundum and rubies .
biography
Verneuil was born in Dunkirk in 1856, the son of a watchmaker. At the age of 17 he became an assistant to the chemist Edmond Frémy , from whom he received his doctorate in 1886 . In 1892 he became a professor of applied and organic chemistry at the Natural History Museum in Paris , where he worked for 13 years. He dealt with the production of synthetic rubies, the chemistry of selenium , the phosphorescence of zinc blende , the chemistry of rare earth metals and the production of glasses with a high refractive index .
Verneuil began making synthetic rubies as early as 1886 and achieved acceptable results within six years. He sealed his notes and deposited them at the Paris Academy of Sciences in 1891 and 1892. However, he did not publish the results of the work until 1902.
