Book excerpt: Focusing on the lives and relationships behind their magnificent careers, The Curies is the first biography to trace the entire Curie dynasty, from Pierre and Marie’s fruitful union and achievements to the lives and accomplishments of their two daughters, Irène and Eve, and son-in-law Frederic Joliot-Curie. Biographer Denis Brian digs deep beneath the headlines and legends to reveal the Curies’ multigenerational saga in its entirety, featuring new, never-before-published personal information as well as newly revealed correspondence and diary excerpts. Brimming with endearing and often amusing anecdotes about this much-misunderstood clan, The Curies reveals a family as closely intertwined in their private lives as they were in their professional endeavors.
