When Marie Curie discovered radioactivity, she kick-started the field of atomic physics and inspired two other female physicists whose work gave rise to the atomic age. Her daughter, Irene (and son-in-law, Frederic) Joliot-Curie, discovered a method of inducing artificial radioactivity. And Austrian-born Lise Meitner figured out nuclear fission. Lise Meitner was twenty years Irene Joliot-Curie's senior, but Austrian law delayed her education by a decade, making the two colleagues. And there are
