Because the origins are all screwed up... Read on!
In the case of "aluminum" (as I will spell it because this is, after all, my column), we can pin the whole mess on Sir Humphry Davy, the English chemist who discovered the stuff back in 1807. Indulging in the perversity of which historical figures seem fond, Davy named his discovery not "aluminum," nor even "aluminium," but "alumium," basing the term on the Latin "alumen," meaning "alum," a substance drawn from the same mineral that had been used since ancient times for dyeing hides and the like. This is all a bit confusing, but we can take comfort in the fact that Davy was apparently a bit befuddled too. Around 1812 he decided that the proper name of his discovery was not "alumium," but actually "aluminum." Almost immediately Davy was besieged by other scientists who pointed out that if Davy would just add an "i" to make the term "aluminium," it would fall into line with such other substance names as "sodium" and "calcium" and, in their words, "sound more classical." So Davy named it yet again, this time to "aluminium," and the "ium" form became standard in both the U.S. and Great Britain.
Unfortunately, many people in the U.S. had evidently stopped listening by that point and continued to call the stuff "aluminum," and this spelling became so widespread that it was eventually adopted as the standard in the U.S. "Aluminium," however, is the official spelling used by international chemical societies. One hopes that Sir Humphry Davy, wherever he may be, is at last happy.
