Fermentation caused by living things? Balderdash!

Small Things Considered is the very endearing blog of the American Society for Microbiology and, like all microbiology, it occasionally touches on alcoholic fermentation. This week, Elio unearthed a hilarious spoof from the early days of fermentation science. Two acclaimed chemists (Justus Liebig and Frederich Wöhler published it in 1839 to make fun of their competitors’ obviously stupid notion that living microorganisms are responsible for the process of fermentation — really, what self-respecting chemist could believe that nonsense! Their imaginings around what those microorganisms might be doing is made even funnier by how close they came — entirely by accident — to the truth. It’s a good laugh, but it’s also a good reminder that so much of what seems patently obvious seemed patent nonsense to our predecessors…and that it can be hard to tell what parts of what we know today might well be balderdash in another hundred years.
