In 1885, he graduated from Oberlin College in Ohio.<\/p>\n\n\n\n

On 23 February 1886, the inventor and engineer produced the first samples of aluminium <\/a>using a method he had developed to make aluminium cheaper to produce. This made aluminium the first metal to achieve widespread use since the prehistoric discovery of iron.<\/p>\n\n\n\n

Hall made most of his instruments and prepared his chemicals, although he also had the help of his older sister Julia.<\/p>\n\n\n\n

His basic invention involved passing an electric current through a bath of alumina dissolved in cryolite; the newly formed aluminium accumulated at the bottom of the retort.<\/p>\n\n\n\n

On 9 July 1886, Hall applied for his first patent.<\/a> This process was also discovered almost at the same time by the Frenchman Paul H\u00e9roult and has come to be known as the \u2018Hall-H\u00e9roult process\u2019. It succeeded in lowering the price of aluminium by a factor of 200, making it affordable for many practical uses.<\/p>\n\n\n\n

When he could not get funding to continue his research, he moved to Pittsburgh (Pennsylvania, USA) where he contacted one of the best-known metallurgists of the time, Alfred Hunt. The two founded the Reduction Company of Pittsburgh, which opened the first large-scale aluminium production plants. Years later it became the Aluminum Company of America and then Alco. Hall was a major shareholder and became wealthy.<\/p>\n\n\n\n

In 1900, annual aluminium production reached about 8,000 tons, and, today, more aluminium is produced than all other non-ferrous metals combined.<\/p>\n\n\n\n

In 1911, he won the Perkin Medal, the highest award for American industrial chemistry.<\/p>\n\n\n\n

In 1997, the American Chemical Society designated the production of aluminium by electrochemistry discovered by Charles Martin Hall as a National Historic Chemical Landmark.<\/p>\n\n\n\n

For the rest of his life, he continued his research and obtained 22 US patents, mostly on aluminium production.<\/p>\n\n\n\n

He also served on the Board of Trustees of Oberlin College and was president of Alco until he died in 1914.<\/p>\n\n\n

Hall has been one of Oberlin College's most important benefactors and has an aluminium statue that, because of its light weight, students joke about moving it around. As a result, it is now attached to a large granite slab and located more permanently on the first floor of Oberlin's new science centre, where students continue to decorate it at Christmas and other occasions.<\/p>\n","protected":false},"excerpt":{"rendered":"
