Two men are credited today with the discovery of microorganisms using primitive microscopes: Robert Hooke who described the fruiting structures of molds in 1665 and Antoni van Leeuwenhoek who is credited with the discovery of bacteria in 1676. In 1673, his observations about stings of bees were published in the Royal Society's journal. Even before microorganisms were discovered, scientists suspected their existence. The word bacteria is the plural of the New Latin bacterium, which is the latinisation of the Greek βακτήριον (bakterion), the diminutive of βακτηρία (bakteria), meaning "staff, cane", because the first ones to be discovered were rod-shaped. These still exist today and it is obvious that, as well as algae and other single-celled plants and animals, he also saw some of the larger bacteria. Spontaneous generation of bacteria and other organisms was thought to be the driving process of putrefaction. It's the best defense against spreading disease.
