The New Dictionary of Scientific Biography is the first major expansion of the classic Dictionary of Scientific Biography, and features more than 800 completely new articles. This work extends, complements, and comments upon the original Dictionary of Scientific Biography, which contains thousands of biographies of mathematicians and natural scientists from all countries and from all historical periods. The Dictionary of Scientific Biography presents an accurate and reliable narrative of the development of science, not as a mere accumulation of technical information but as the collective accomplishment that has ordered our understanding of nature. More than 500 of the new articles are devoted to scientists deceased since 1980 and not previously treated in the Dictionary of Scientific Biography including Hans Bethe, Francis Crick, Richard Feynman, Stephen Jay Gould, Fred Hoyle, Mary Leakey, Konrad Lorenz, Barbara McClintock, Linus Pauling, Andrei Sakharov, B. F. Skinner, and Edward Teller. There are also more than 75 articles on figures overlooked in the original Dictionary of Scientific Biography (from Chrysippus to Kinsey) and 250 commentaries on important careers that have inspired new research and interpretation (from Archimedes and Aristotle to Darwin, Einstein, and Oppenheimer).
