File Edmond Fr my.jpg right thumb 200px Edmond Fremy Edmond Fr my 28 February 1814 3 February 1894 was a France French chemist . He is perhaps best known today for Fr my s salt , a strong oxidizing agent which he discovered in 1845. Fremy s salt is a long lived free radical that finds use as a standard in electron paramagnetic resonance spectroscopy. Life and work Fr my was born at Versailles , entered Joseph Louis Gay Lussac s laboratory in 1831, and was employed at the cole Polytechnique in 1834 and at the Coll ge de France in 1837. His next post was that of repetileur at the cole Polytechnique, where in 1846 he was appointed professor, and in 1850 he succeeded Gay Lussac in the chair of chemistry at the Mus um national d histoire naturelle , of which he later became director 1879 1891 after Michel Eug ne Chevreul . He died in Paris. sfn Chisholm 1911 p 98 Fr my s work included investigations of osmic acid, of the ferrates, stannate s, plumbate s, &c., and of ozone , attempts to obtain free fluorine by the electrolysis of fused fluorides, and the discovery of anhydrous hydrofluoric acid and of a series of acides suiphazots, the precise nature of which long remained a matter of discussion. He also studied the coloring of leaves and flowers, the composition of bone , cerebral matter, and other animal substances, and the processes of Fermentation biochemistry fermentation , in which he was an opponent of Louis Pasteur Pasteur s views. sfn Chisholm 1911 p 98 Keenly alive to the importance ...

Auguste Victor Louis Verneuil 3 November 1856 27 April 1913 was a French chemist best known for inventing the first commercially viable process for the manufacture of synthetic gemstone s. In 1902 he discovered the flame fusion process, today called the Verneuil process , which remains in use today as an inexpensive means of making artificial corundum , or ruby rubies . Biography Verneuil was born in Dunkirk , France, in 1856. He was the son of a watchmaker mechanic. When he was 17, chemist Edmond Fremy accepted him as a laboratory assistant. He received his bachelor degree in 1875, his master s in 1880 and his PhD in 1886. In 1892 he became a professor of applied chemistry in the organic chemistry section of the Paris Museum of Natural History Museum of Natural History in Paris , where he worked for 13 years. He studied methods to synthesize ruby , the chemistry of selenium , the phosphorescence of zincblende , the chemistry of rare earth element s, the purification of glycerine and the production of high refractive index glass . He also taught chemistry at various high schools and colleges. Verneuil began working on the synthesis of rubies by flame fusion as far back as 1886 and came to a result within six years, depositing his sealed notes at the Paris Academy of Science in 1891 and 1892, but only announcing his discovery in 1902.
