We know how many abortions have been perpetrated in the United States … but does anyone know what the WORLDWIDE number is?
How many potential geniuses have we killed off?
We are so arrogant at totally ignoring the role of genius in improving the human condition.
We take everything for granted!!
Aluminum … we take it for granted … but it was once more costly than GOLD!
Until Charles Hall and Paul Héroult came along, that is.

Charles Martin Hall and Paul Héroult might have developed the more practical process after Deville.
Before the Hall-Héroult process was developed in the late 1880s, aluminium was exceedingly difficult to extract from its various ores. This made pure aluminium more valuable than gold.[49] Bars of aluminium were exhibited at the Exposition Universelle of 1855.[50] Napoleon III of France is reputed to have given a banquet where the most honoured guests were given aluminium utensils, while the others made do with gold.[51][52]
Aluminium was selected as the material to be used for the 100 ounce (2.8 kg) capstone of the Washington Monument in 1884, a time when one ounce (30 grams) cost the daily wage of a common worker on the project.[53] The capstone, which was set in place on December 6, 1884, in an elaborate dedication ceremony, was the largest single piece of aluminium cast at the time, when aluminium was as expensive as silver.[53]
The Cowles companies supplied aluminium alloy in quantity in the United States and England using smelters like the furnace of Carl Wilhelm Siemens by 1886.[54][55][56] Charles Martin Hall of Ohio in the U.S. and Paul Héroult of France independently developed the Hall-Héroult electrolytic process that made extracting aluminium from minerals cheaper and is now the principal method used worldwide. Hall’s process,[57] in 1888 with the financial backing of Alfred E. Hunt, started the Pittsburgh Reduction Company today known as Alcoa. Héroult’s process was in production by 1889 in Switzerland at Aluminium Industrie, now Alcan, and at British Aluminium, now Luxfer Group and Alcoa, by 1896 in Scotland.[58]
