Gr 5-8-These high-quality biographies provide in-depth looks at the background and education of the scientists, followed by the trial and error that they went through before achieving success. Their victories and achievements are also detailed in concise descriptions of the evolution of their inventions and the impact they have made on today's world. Full-color and black-and-white photos, illustrations, and reproductions appear throughout. The wide margins contain picture captions, quotations, and sidebars. Solid additions for science assignments and reports.-John A. Clexton, Grosse Pointe Public Library, MI Copyright 2001 Cahners Business Information.
