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.
