Aluminum or Aluminium?

Atomic number 13, symbol Al, Pop cans and car bodies are made of this light metal. Americans spell it aluminum and pronounce it "uh-loom-i-num". The British spell it aluminium and pronounce it "al-yoo-min-ee-um". So who is correct?

Alumin(i)um was discovered by Humphrey Davy in 1808, and he called it "alumium" because of the already known Al salt, alum. In 1812 he changed the name to "aluminum" because I guess he thought it sounded better. At the same time, a group of scientists in Britain changed the spelling to "aluminium" because they thought the "-ium" ending made it sound more like the other elements.

The discoverer himself called it aluminum, and he was born in Britain. Those who decided it needed to sound more like the other elements and changed the name from underneath him were rude and presumptuous. By their logic, my wedding ring should be made of goldium and my good flatware made of silverium.

Based on the simple rule that the discoverer or inventor of something has the naming rights and in honor of Humphrey Davy, this point goes to the Americans. The foil covering your leftover meatloaf is aluminum foil, not aluminium foil.
