Description: We have the engineer Charles Stark Draper to thank for advances in navigational systems for ships, airplanes, and missiles. The period in which Draper worked was overshadowed by war. It includes many military inventions, such as the jet engine and the first atomic bomb. However, it was also a time of important progress in communications, space exploration, health, and more. In the late 1900s, Gertrude B. Elion developed important drugs for the treatment of major diseases, including leukemia, malaria, and AIDS. Photographs support the in-depth biographies of influential inventors from this period and inspire readers with their fascinating creations.
