Hans Christian Oersted, a Danish chemist, was the first to produce tiny amounts of aluminum in 1825, German chemist Friedrich WÃ¶hler developed a method that produced enough to study the metal's basic properties in 1845.
Sir Humphry made a bit of a mess of naming this new element, at first spelling it alumium (this was in 1807) then changing it to aluminum, and finally settling on aluminium in 1812.
