Baldwin's biography of Dr. Helen Taussig is an admiring testimonial to the woman who became the world's foremost authority on pediatric cardiology, doing so despite personal and societal difficulty. Taussig overcame not only the gender discrimination of the early 1920s, which prevented her from being admitted to Harvard's medical school, but also a severe learning disability and deafness. Her enlightening story provides a model of personal courage. In addition, it affords an interesting look at the barriers women encountered in the first half of this century and a glimpse of the painstaking process of medical research and the people involved. A well-done book, recommended for school and public libraries in need of biographies of scientists and of women in professional fields. To be illustrated with photographs; further readings are appended.
