Irène Joliot-Curie
In 1935, he received a six-month scholarship from the French government to study in France, where he moved with his freshly married bride Branka (nee Božinović). With professor Jovanović's references, he was hired at the Radium Institute in Paris, and he would ultimately spend five years in France. He worked with Irène Joliot-Curie and Frédéric Joliot-Curie on interactions of neutrons in the chemical physics of heavy elements, and they published a number of papers in 1938 and 1939. This turned out to be an important step in the discovery of nuclear fission. Together with Irène Joliot-Curie, Savić was nominated for the Nobel Prize in Physics, but the prize hadn't been awarded during World War II. The same issues were researched by a number of other scientists, including Enrico Fermi, Lise Meitner, Otto Hahn, Fritz Strassmann and others, but in 1944 the Nobel Prize was awarded for the discovery of fission only to Hahn.
