Marie Curie and Her Daughters is a biography that tells the story not only the quite well-known Madame Curie, but also her two daughters, Irène and Eve. The three of them broke barriers in chemistry and physics, saved lives by introducing x-rays during World War 1, and travelled extensively on speaking tours to educate the public on new developments. This book includes actual letters written by the Curies, and it's a fascinating journey for anyone interested in science or women's history.
