One of the worst things for a scientist is to be right but be early. The Earth goes around the Sun? Burn him at the stake! You want doctors to wash their hands between patients? Get out of my hospital. So there are creatures too small to see, causing cholera in the water? Drink up. Although all these visionaries and countless others had it right, they suffered for their genius, and were vindicated only too late to enjoy it.
