Today (December 27, 1914) is the Memorial Day of Charles Martin Hall, the inventor of Aluminium.

Charles Martin Hall was born on December 6, 1863, in Thompson, Ohio. His father was Himan Basat Hall. Mother is Sophronia H. Brooke Hall. In 1873 his family moved to the Oberlin area. There Martin Hall began his higher education. As he was interested in music, he took music as an adjunct. He joined Oberlin College in 1880 and received his bachelor's degree in art in 1885. Although he graduated with a degree in art, he was still interested in scientific experiments and research. His professor, Frank Fanning Jewett, once pointed out a small piece of aluminium and explained that those who made it the easiest way would be very rich. Driven by this, Martin embarked on an experiment to explore it.

Martin used the laboratory of Oberlin College for his research. Later his laboratory was a room set up in wood at the back of his house. With the support and cooperation of his sister and Professor Jewelt, he continued to carry out his scientific experiments. He extracted aluminium on February 23, 1886, after eight years of painstaking research. He dissolved alumina in cryolite and passed electricity through it to extract the aluminium metal. He applied for a patent for his invention in 1886. Patent Number (s) 400, 665. In the same year, Paul Harold of France similarly extracted aluminium.

Martin Hall moved to Pittsburgh and started the Pittsburgh Reduction Company in 1888 with the help of some investors there. The company is commercially engaged in the production of aluminium. Aluminium production multiplied due to Martin Hall's production activity. The fall in aluminium prices was due to easy availability. The company has been operating under the name Aluminum Company of America (Alcoa) since 1907. Martin's 25 years of hard work led to tremendous growth in the aluminium industry.

He was awarded the Berkin Medal in recognition of his work. At the Oberlin College where he graduated, the college administration specialized in installing an aluminium statue of him in granite. Martin Hall's discovery about the extraction of aluminium, which is now widely used as an alternative to iron, has changed the history of metals. Martin Hall passed away on December 27, 1914, at the age of 51, on Titona Beach, Florida, after he discovered aluminium, and available metal became cheaper.
