The first of four volumes in the landmark Lives and Legacies Oryx Press series, Scientists, Mathematicians, and Inventors profiles approximately 200 men and women who changed the world by leaving lasting legacies in their fields. It fills a gap in the biographical reference shelf by offering far more than basic facts about a scientist's life and work-each entry describes not only the immediate effects of the individual's discoveries, but their impact on later scientific findings as well. Each entry contains a timeline listing important dates in the biographee's life as well as a bibliography of the most important works on the subject. A master timeline chronicling major events in scientific exploration and an annotated general bibliography are also included.
