comment
↑ Davy's 1812 written usage of the word aluminum was predated by other authors' usage of aluminium . However, Davy is often mentioned as the person who named the element; he was the first to coin a name for aluminium: he used alumium in 1808. Other authors did not accept that name, choosing aluminium instead. See below for more details.
