French chemist best known for his discovery of hydrogen fluoride and investigations of fluorine compounds. Among other compounds, Frémy investigated those of iron, tin, and lead. He also studied osmic acid, ozone, the colouring substances of leaves and flowers, and the composition of animal substances. He applied chemistry to the commercial saponification of fats, and to the technology of iron, steel, sulfuric acid, glass and paper. He tried, but failed, to isolate the element fluorine. He also failed in attempts to make crystals of aluminium oxide, but instead found he could create rubies.
