Frédéric Joliot-Curie was born Jean Frédéric Joliot on March 19, 1900, in Paris. He studied at the École de Physique et Chimie Industrielles de Paris, graduating at the top of his class in 1923. In 1925, he became an assistant to Marie Curie at the Radium Institute, where he met and later married her daughter, Irène Curie, in 1926. Together, they formed one of the most famous scientific partnerships of the 20th century.

His early research focused on radio-elements and atomic structure. In collaboration with Irène, Joliot-Curie made their most celebrated discovery in 1934: artificial radioactivity. By bombarding elements with alpha particles, they created radioactive isotopes not found in nature. This breakthrough earned them the 1935 Nobel Prize in Chemistry, cementing their place in scientific history.

Beyond this, Joliot-Curie contributed significantly to nuclear physics. He became a professor at the Collège de France in 1937 and led pioneering work on nuclear chain reactions. His team built the first cyclotron in Western Europe and laid the groundwork for nuclear reactor development. During World War II, as Nazi forces occupied Paris, he safeguarded vital research by smuggling documents and materials out of France with colleagues Lew Kowarski and Hans Halban.
