Only nine of the more than 300 Nobel prizes awarded in science since 1901 have been won by women, notes science writer Bertsch as she sets the context for the biographical essays that follow. Examining the careers and lives of 14 women scientists "who either won a Nobel Prize or played a crucial role in a Nobel winning project," she movingly depicts their battles against gender discrimination for recognition and respect and she describes the self-conflict about their roles. Subjects range from Marie Curie (1867-1934) to such contemporaries as Rosalyn Yalow, awarded a Nobel Prize in 1977 for her work as a medical physicist, and Jocelyn Bell Burnell, an astrophysicist credited, at the age of 24, with the 1968 discovery of pulsars, who made large personal sacrifices for her science.
