Marie Curie brought the X-ray into use when France found themselves at war. She found that the best thing that she could do to help was to provide X-ray machines for all of the wounded soldiers that were brought into the hospital. Marie Curie and many helpers eventually got 20 cars equipped with X-ray equipment and over 200 hospital rooms each equipped with X-ray machines. Marie Curie is still relevant today because as far as I know X-rays are still used.
