" In the mid-1800s, Dr. Ignaz Philipp Semmelweis noticed that new mothers who were treated by midwives fared much better than those who were treated by trainee doctors, who also handled and dissected cadavers. He believed that sticking one’s hands into a dead body and then directly into a laboring woman was dangerous. So, Semmelweis issued a mandate that hands must be washed between the two activities. And it worked! Rates of infection dropped from one in ten to one in a hundred within the first few months. Unfortunately, the finding was rejected by much of the medical establishment of the time. One of the reasons it was so hard to get doctors to wash up? The stench of “hospital odor” on their hands was a mark of prestige. They called it “good old hospital stink.” Quite simply, decayed corpse smell was a badge of honor they had no intention of removing. "
