Nobel Prize laureate physicist and chemist

A brilliant scientist herself, she is the elder daughter of Marie Curie. Iréne had always been interested in chemistry; so having graduated from secondary school graduation, she immediately became her mother's assistant in the Radium Institute in Paris. She submitted her doctoral thesis on the alpha rays of polonium in 1925.

She met Frédéric Joliot, her future husband and research partner in the Radium Institute. In their experiment, they bombarded aluminium with alpha particles, and produced a substance the radiation of which, similar to natural radioactivity, decreased. They were the first to produce synthetic radioactive substance. In 1934, the couple started to study positron emission. Shared with her husband, Iréne received the Nobel Prize in Chemistry in 1935.
