When he was a student at Oberlin College, he was inspired by
a chemistry professor’s remark that if “anyone should invent a process by which
aluminum could be produced on a commercial scale, he could build a large
fortune.”
At the time,
aluminum was extremely difficult and costly to liberate from its oxide-bound
form in nature.
In 1866,
working with simple chemicals, the young student invented a smelting process
that remains the basis for producing aluminum to this day.
Demand had to
be cultivated as much as the technology.
Few industrialists saw a need for aluminum.
This didn’t
stop the student from founding Alcoa, and in a few years aluminum was being
used for electric cable, kitchen utensils explosives and automobile manufacturing.
At the time
of his death, Charles Martin Hall was history’s wealthiest inventor.
