Gr 5-8 Bolden's broad view of STEM, including profiles of physicians and medical professionals, is aimed at middle grade readers interested in science careers. The book opens with a section ("In the Vanguard") devoted to black women who battled racism and discrimination following the Civil War. Rebecca Crumpler, who worked as a nurse, was born free in Delaware. She decided to move to Virginia right after the war to assist with the injured. Many women in the book earned pioneer status: the first to pass a state medical exam, graduate from medical college, practice medicine, or head a science department. Most poignant are the trailblazers whose discoveries, like a humane treatment for leprosy, resulted in their deaths from side effects of the experiment. The second section celebrates those who entered aviation, bacteriology, mathematics, and architecture. The third section features geneticists, marine biologists, and the inventor of the device to remove cataracts. Milestones that mark each era (the Declaration of Sentiments written in 1848 to advance women's rights; the passage of the Equal Employment Opportunity Commission in 1964) are noted. Even though it is a pleasure to discover so many overlooked geniuses, including Angie Lena Turner King (Katherine Johnson's mentor), it's sobering to learn that only one percent of black women earned engineering degrees in 2015. VERDICT Bolden, a master of the collective biography, presents an impeccably-researched call to action, imploring black girls to fight the racial and gender imbalance that plagues the STEM field.

This sweeping collective biography of American Black women in STEM careers brings the wide variety of their achievements into focus for middle-graders in this work by Coretta Scott King Honor Book author Bolden (Inventing Victoria, 2019). Including women from professions as diverse as computer science, marine biology, chemical engineering, and the medical sciences, each figure is given a few pages worth of description of their early personal life, educational pursuits, and career highlights, making for a somewhat formulaic approach to each woman's biography. Though the profiles necessarily lack detail, Bolden more than makes up for it in the variety of women featured, from the mid-1800s to today and including many unfamiliar names, such as video game developer Lisette Titre-Montgomery or marine biologist Joan Murrell Owens. Pullouts of vocabulary etymologies, quotes, and plenty of pictures of its subjects help bolster the biographies. Young people are sure to find intriguing role models among the many STEM all-stars in this comprehensive look at the achievements of gifted Black scientists and doctors. Final art not seen.
