Which of Marie Curie's daughters became a Nobel laureate?

Marie Curie's daughter who became a Nobel laureate was Irène Joliot-Curie.

Born Irène Curie in Paris in 1897, she followed her mother into physics and chemistry. In 1935, Irène and her husband, Frédéric Joliot-Curie, received the Nobel Prize in Chemistry for discovering artificial, or induced, radioactivity.

This made Irène and Marie the only mother-daughter pair to win Nobel Prizes. Marie had won the Physics Prize in 1903 and the Chemistry Prize in 1911, while Irène's award came in Chemistry. Irène's younger sister, Ève Curie, was a writer and journalist, not a scientist or Nobel laureate.

A related family fact is that Irène's children also became scientists: Hélène Langevin-Joliot became a nuclear physicist, and Pierre Joliot became a biochemist.
