Charles Martin Hall
(6 Dec 1863 - 27 Dec 1914)

American chemist who invented (1886) an inexpensive electro-chemical method to extract aluminium from its ore. The process quickly enabled commercial production of this metal, at prices competitive with steel and copper. Aluminium, once a precious metal used for fine jewelry, by 1914 was down to 18 cents a pound.


Science Quotes by Charles Martin Hall (3 quotes)

I read about Deville’s work in France, and found the statement that every clay bank was a mine of aluminum, and that the metal was as costly as silver. I soon after began to think of processes for making aluminum cheaply.

My first knowledge of chemistry was gained as a schoolboy at Oberlin, Ohio, from reading a book on chemistry which my father studied in college in the forties. I still have the book.

The idea formed itself in my mind that if I could get a solution of alumina in something which contained no water, and in a solvent which was chemically more stable than the alumina, this would probably give a bath from which aluminum could be obtained by electrolysis.

Quotes by others about Charles Martin Hall (2)

Aluminium’s sixty-year reign as the world’s most precious substance was glorious, but soon an American chemist [Charles Hall] ruined everything.
Sam Kean
In The Disappearing Spoon: And Other True Tales of Madness, Love, and the History of the World from the Periodic Table of the Elements (2010), 235.
Science quotes on:  |  Aluminum (13)  |  Precious (42)  |  Reign (24)

Aluminum has been called the sustainability nutrient of the world, and for good reason. Consider that 75% of all the aluminum made since 1886 is still in use. So from a sustainability standpoint alone, yes, [Charles] Hall really did become that benefactor to humanity—big time.
As quoted in 'Alcoa Co-Founder Charles Hall Smelt Success' (20 Jul 2012), article on investors.com website.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
