Who discovered aluminum

It is a common sense that Aluminum occurs naturally only in compounds, never as a pure metal,removing aluminum from its compounds is quite difficult. An inexpensive method for producing pure aluminum was not developed until 1886.

The name of aluminium can also be called as aluminum,so why are these two names?
Sir Humphry Davy proposed the name aluminum, back before the element was officially discovered. However, the name 'aluminium' was adopted to conform with the -ium names of most other elements.

In 1925, the American Chemical Society decided to go back to the original aluminum, so the United States uses a different name from most other countries.

Now let us date back to the history of the aluminium discovery.
Guyton de Morveau (1761) named alum a base which had been known to the ancient Greeks and Romans, by the name alumine.

In 1808, Humphry Davy identified the existence of the metal in alum, which he at first named alumium and later aluminum.
Davy knew aluminum existed, but he didn't isolate the element.
Friedrich Wöhler isolated aluminum in 1827 by mixing anhydrous aluminium chloride with potassium. Actually, though, the metal was produced two years earlier, though in impure form, by the Danish physicist and chemist Hans Christian Ørsted.

Depending on your source, the discovery of aluminum is credited to either Ørsted or Wöhler.
