Which chemical elements did Marie and Pierre Curie discover?

It is a shame that they both died from radiation poisoning; however, their research was monumental with their discovery of radium and polonium.

David, Pierre Currie died in a traffic accident. A beer dray ran him over. He was middle aged. Marie died in her sixties, of cancer, but not very young for the day. It is sad when someone dies.

Player Jellybean - Sorry, but I don't understand your comment. Do you mean that you object to something in David's comment?
