Carl Josef Bayer was a chemist from Austria-Hungary who invented and named the Bayer process of extracting alumina from bauxite, essential to this day to the economical production of aluminium. Born in 1847, he studied chemistry under Robert Bunsen at Heidelberg University and took his doctorate in 1871. While working in Saint Petersburg to provide alumina to the textile industry, he discovered in 1887 that aluminium hydroxide precipitated from an alkaline solution is crystalline and easy to filter and wash, and in 1888 he patented his four stage process. Together with the Hall-Heroult process, his method caused the price of aluminium to drop by about 80 percent. He died in 1904.
