On today's podcast, I had the honor of talking to E.B. Fred Professor of Natural Sciences Emeritus at UW–Madison and author of the book, Robert Koch--A Life in Medicine and Bacteriology, Thomas Brock, PhD about the titan of microbiology, Robert Koch.

In this show, I asked the 93-year-old microbiologist about Koch's life prior to microbiology, his relationship with Louis Pasteur and several of Koch's major contributions to bacteriology from the discovery of the agent of tuberculosis in 1882 to the famous postulates that bear his name.
