In 1967, it was 100 years since the birth of Marie Curie, a famous Polish scientist who made important discoveries in physics and helped begin the era of atomic energy.

Marie Curie’s daughter, Irene, was also very interested in science and her mother’s work. Marie taught her everything she knew about radiology. When Irene was 29 years old, she married Frederic Joliot, who was also a talented scientist. They both worked at the Institute of Radium, which Marie and her husband had founded.

Together, Irene and Frederic continued the research that Marie had started. In 1935, they won the Nobel Prize for discovering artificial radioactivity. Marie was able to see their great achievements, but sadly, she died just before they received the award.

We respect both generations of the Curie family not only for their discoveries but also for their dedication to science. Marie, her daughter Irene, and her son-in-law Frederic all died from radiation sickness because they spent many years working with radioactive materials.

Frederic Joliot-Curie was not only a famous scientist but also an important leader of the progressive movement.
