Born in Paris, France, he was a graduate of the École Supérieure de Physique et de Chimie Industrielles de la Ville de Paris. In 1925 he became an assistant to Marie Curie, at the Radium Institute. He fell in love with her daughter Irène Curie, and soon after their marriage in 1926 they both changed their surnames to Joliot-Curie. At the insistence of Marie,

Pierre Curie was increasingly intrigued by her work. By mid-1898 he was so invested in it that he decided to drop his work on crystals and to join her. She was acutely aware of the importance of promptly publishing her discoveries and thus establishing her priority. Had not Becquerel, two years earlier, presented his discovery to the "Académie des Sciences" the day after he made it, credit for the discovery of radioactivity, and even a Nobel Prize, would instead
