"On one of our regular Friday night visits to the Seventy-third Street public library, my father encourage me to borrow 's celebrated 1926 book, Microbe Hunters. In it were fascinating stories of how infectious diseases were being conquered by scientists who went after bad germs with the same tenacity as Sherlock Holmes pursuing the evil Dr. Moriarity. Some months later I brought home Arrowsmith, in which Sinclair Lewis, helped by Paul de Kruif as expert consultant, relates the never-realized hope of his hero to save victims from by treating then with bacteria-killing viruses. The 's youth gripped me and made me realize that science could be like : a young man's game whose stars made their mark in their early twenties."
