My favorite example of this is Pasteur's revolutionary work in immunology itself: A careful reading of Pasteur’s presentations to the Academy of Sciences reveals that Pasteur was entirely mistaken as to how immunity occurs, in that he reasoned, as a good microbiologist would, that appropriately attenuated microbes would deplete the host of vital trace nutrients absolutely required for their viability and growth, and not an active response on the part of the host. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3342039/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3342039/
