Sir Humphry Davy
Sir Humphry Davy was born in 1778 in Penzance in Cornwall. He is known for his work in electrochemistry, discovery of the existence of aluminium and invention of a miner’s safety lamp. He prepared nitrous oxide, which is commonly known as the laughing gas, and was subsequently hired as an assistant lecturer in chemistry at the Royal Institution. He became a fellow of the Royal Society in 1803 and was awarded its Copley Medal in 1805.

Davy used the process of electrolysis to isolate a series of substances for the first time - potassium and sodium in 1807 and calcium, strontium, barium and magnesium the following year. He established the existence of aluminium in 1808. Davy was knighted in 1812 in recognition of his seminal contributions in science.
Friedrich Wohler
Freidrich Wohler was a German chemist, who is famous for his synthesis of urea and isolation of many chemical elements. He co-discovered beryllium, silicon and silicon nitride and systhesized calcium carbide. In 1827, Wohler extracted aluminium as a powder by reacting potassium with anhydrous aluminium chloride. In 1845, he established the lightness of aluminium.
Henri Saint-Clair Deville
Henri Saint-Claire Deville was a French chemist. He discovered anhydrous nitric acid (nitrogen pentoxide) in 1849 and he succeeded in obtaining metallic aluminium in 1855 and displayed a solid bar of aluminium at a Paris exhibition in the same year. He devised a method by which the metal could be prepared on a large scale by the aid of sodium, the manufacturing process of which was developed by him.

Deville collaborated with Friedrich Wohler to discover silicon nitride in 1857 and worked on platinum metals with H.J. Debray. With L. J. Troost, he devised a method for determining vapour densities at temperatures up to 1400˚C and investigated the allotropic forms of silicon and boron with Friedrich Wohler.
Karl Josef Bayer
Karl Josef Bayer was an Austrian chemist, known for his invention of the Bayer process, by which alumina is extracted from bauxite. In 1887, Bayer discovered that aluminium hydroxide precipitated from an alkaline solution was crystalline and could be filtered and washed more easily than that precipitated from an acid medium by neutralization. In 1889, Bayer developed and patented the Bayer process of extracting alumina from bauxite. The Bayer process helped in reducing the price of aluminium significantly.
Charles Martin Hall
Charles Martin Hall was an American scientist best-known for inventing a process that could produce aluminium cheaply. Hall produced the first samples of aluminium in 1886 and the process involved passing an electric current through alumina dissolved in cryolite. Around the same time, French scientist Paul Heroult produced aluminium using the same process and therefore, this process of making aluminium is known as the Hall-Heroult process. The Hall-Heroult process reduced the price of aluminium drastically and made it more affordable.

Hall and Alfred E. Hunt formed the Reduction Company of Pittsburgh, which opened the first large-scale aluminum production plants. The Reduction Company later became the Aluminum Company of America (ALCOA). Hall won the Perkin Medal, the highest award in American industrial chemistry, in 1911.
Paul Heroult
Paul Heroult was a French scientist best known for the discovery of the Hall-Heroult electrolysis process for making aluminium. He made this invention in 1886, the same year in which American scientist Charles Martin Hall invested the same process for making aluminium. The process is therefore known as the Hall-Heroult process.

Heroult also invented the electric arc furnace for steel in 1900 and a self-sustained conduit, which is still used to bring water down from mountains and across rivers to hydraulic power plants.
Ron Knapp
Mr. Ron Knapp is the Secretary General of the International Aluminium Institute. He was earlier the CEO of the Australian Aluminium Council.
Artem Volynets
Mr. Artem Volynets is the Chairman of International Aluminium Institute
Rudolph P. Huber
Mr. Rudolph P. Huber is the Chairman of the European Aluminium Association. He took over the current position with effect from 1st January, 2009 and will serve a term of two years.
