Last night I was sitting and thinking about the biggest medical advancement ever made. Certainly we have done many great things over the years but I think without question the best was hand washing by Ignaz Semmelweis. Interesting he was wrong about the root cause of the problem, but of course you don’t need to know why hand washing is important for it to work. Also interesting is that despite clear proof that it worked he was dismissed by his contemporaries. He died before the germ theory by Pasteur was developed; he could have had a better explanation for why hand washing works and further developed his idea. How many people have been touched by Ignaz’s insight? Billions +? Ignaz is one of the giants that no one remembers and no even knows his name. Hats off to you Ignaz Semmelweis.
