Died 27 Dec 1914 at age 51 (born 6 Dec 1863).American chemist who invented the inexpensive electrolytic method of extracting aluminium from its ore, enabling the wide commercial use of this metal. While a young chemist, he experimented in a woodshed, intent upon finding a method for separating aluminum from its ore. At first, he was unsuccessful, but then realized that he needed a nonaqueous solvent for the aluminum oxide during electrolysis. On 23 Feb 1886, Hall found that molten cryolite (the mineral sodium aluminum fluoride) was a suitable solvent and using carbon electrodes with home-made batteries, he produced his first small globules of aluminum. By 1914, Hall's process had brought the cost of aluminium, once a precious metal used for fine jewelry, down to 18 cents a pound.«
