Hans Zinsser taught bacteriology and immunology at the universities of Stanford and Columbia before going on to teach at the Harvard University Medical School. As well as researching extensively into cholera, allergies and rheumatic fever, he was a pioneer in isolating the micro-organism that causes a form of typhus. To Zinsser, scientific research was high adventure and the investigation of infectious disease, a field of battle. He died in 1940.
