This memoir is a warm intermingling of family story and the atomic bomb's early history with especial emphasis on the growth in understanding of radiation dangers. Dr. Stafford L. Warren, the author's father, sat at the knee of Madame Curie and later, as a Colonel, became head of the Medical Section of the Manhattan Project. He established radiation safety rules, attended the first detonation, headed up the post-war survey of Hiroshima and Nagasaki, and fought with admirals to protect 42,000 personnel in Operations Crossroads at Bikini Atoll.
