There she got a job as a research scientist. While she was doing her research, she met Pierre Currie. Her friendship with this French scientist resulted in their marriage. They worked together and discovered radium. In 1903, Marie and Pierre died won the Nobel Prize for Physics. A few years later, Pierre died in an accident.
