Here's a book that was needed to prove that more was needed to win the war than men and material. It should also make the fact clear that no one branch of the service can claim the whole victory. It was a closely knit coordination of all factors that enabled our unready country to defeat nations armed to the teeth. This book shows the vital part played by science, from insecticides to the Atomic Bomb. From the start, scientists were given access to secret plans and problems. This volume records the history of the Office of Scientific Research, in language for the layman. In the space of months, scientists accomplished what would ordinarily have taken years. New weapons, improvement of old ones; anti-submarine devices; radar; bombs and incendiaries; landing craft and assault weapons; preventive medicine; penicillin -- all this and more, done in vivid and interesting terms.
