In 1903, when Curie finished her PhD at the Sorbonne, her examiners thought that her work was the greatest contribution to science ever made in a PhD thesis. That year, she also won the Nobel Prize with her husband and Henri Becquerel for their work on radiation. She was the first woman to earn a Nobel Prize in physics. A few years later, Pierre was struck by a horse carriage and died. The Sorbonne offered Curie his position as professor of physics at the Sorbonne, making her their first female professor.
In 1911, Marie Curie won her second Nobel Prize, this time in the field of Chemistry for discovering polonium and radium. This would make her the first and only person to win a Nobel Prize in two different fields. Curie became famous for her scientific discoveries and was invited to attend the Solvay Congress in physics with Albert Einstein and other famous scientists.
When World War One broke out, Curie devoted herself to helping soldiers. She realized there was a shortage of X-ray machines, which meant they couldn't help all of the wounded soldiers.
