Irène Joliot-Curie

Irene Curie met her future husband, Frederic Joliot while working as an assistant to her mother at Radium Institute. He shared her interest in science, sports, humanism and arts.

Irene married Frederic in 1926. The duo adopted a hyphenated surname after marriage and were known as Joliot-Curies’. The couple was blessed with two children, a daughter Helena who became a noted physicist and a son Pierre who was a biologist.

During World War II, Joliot-Curie contracted tuberculosis. She was forced to spend several years convalescing in Switzerland. Though she made frequent trips back to France, they were dangerous as she served several detentions.

Irene Joliot Curie was born as Irene Curie to Pierre and Marie Curie on September 12, 1897, in Paris, France.

Academically brilliant, young Curie began her formal education at the age of 10. Within a year, her mathematical skills brought her to prominence. Wanting to put little Curie in a challenging environment so as to make the best use of her academic capabilities, her parents joined ‘The Cooperative’ a private gathering that included some of the most distinguished names in academics in France.

For two years, she studied at the Cooperative, getting trained by some of the most distinguished French scholars. Interestingly, the curriculum of Cooperative did not limit itself to scientific studies alone. In fact, children were taught diverse subjects, right from language to sculpture and even self-expression and play.

Following her training at the Cooperative, Curie enrolled at an orthodox school environment at Collège Sévigné in central Paris. She studied therein for two years, from 1912 to 1914 before enrolling at the Faculty of Science at Sorbonne.

While she was studying for her bachelor’s degree at the Faculty of Science, World War I commenced. Her studies were stalled by the war. During the war, she collaborated with her mother, Marie Curie, who was running 20 mobile field hospitals. Both mother and daughter worked as nurse radiographers, working on the then newly conceived X-Ray equipment.

After her wedding with fellow researcher Frederic Joliot, the duo adopted the surname Joliot-Curie. Since 1928, Joliot-Curie and her husband Frederic combined their research efforts on the study of atomic nuclei.

During the initial years of research, though the husband-wife duo identified positron and neutron, they failed to interpret the same into their results. Later on Carl David Anderson and James Chadwick were credited with the discovery of positron and neutron respectively. In 1932, she was appointed lecturer at the Faculty of Science.

In 1934, Joliot-Curie along with her husband Frederic struck gold with the discovery of artificial radioactivity. They were primarily building on Pierre and Marie Curie’s work, when they finally created isolated naturally occurring radioactive elements. The discovery was a milestone in science.

Joliot-Curies bombarded boron, aluminium, and magnesium with alpha particles. On bombardment, they obtained radioactive isotopes of elements not ordinarily radioactive, namely, 13 of nitrogen, 30 of phosphorus, 27 of silicon and 28 of aluminium. Since these elements are not found naturally, they would decompose easily emitting positive and negative electrons.

The discovery of artificial radioactivity was revolutionary in the field of science. Both Joliot-Curie and her husband sealed their place in scientific history with their finding as creation of artificial radioactive materials assisted in filling up for the huge demand for radioactive element that were then used in medicines. Their discovery allowed the elements to be created quickly, plentifully and at very low cost.

Her most significant contribution to science came with the discovery of artificial radioactivity, which was a milestone in the field of science. The discovery allowed for the creation of short-lived, but easy to create radioactive isotopes from elements such as aluminium, boron, sulphur and phosphorous. These artificially created radioactive isotopes were used in medicine. Also, the production of these unstable atomic nuclei afforded further means for the observation of changes in the atom as these nuclei broke down.
