Great history in this book!

"Three hundred years ago, no one knew germs existed.... that they caused disease.  This is not because people in those days were stupid, but because they did not have microscopes.  "First, then, came the microscope.  After that came the long, slow business of finding out how germs cause disease.  And then came ways of fighting them..." - Navin Sullivan
