Sorry if this has already been cleared up, because I haven't read all the thread pages, but to help clear up the aluminum vs. aluminium controversy, I went to Wikipedia. (Take Wikipedia for what you will.)
One of the first people to identify the base metal of alum was Humphrey Davy, who first called it alumium, but by 1812 had settled on the name aluminum. (He had discovered and named several other elements as well.) Some British political literary journal called Quarterly Review objected, and wanted it called aluminium, thus starting the two camps of naming. But the first full version of the name was aluminum. Sorry, UK residents and Danes.
