|Paramecium captured under the microscope at 400x.|
In 1718 the French math teacher and microscopist Louis Joblot published a description and illustration of a microscopic "Poisson" (translated fish) that he discovered in an infusion of oak bark in water. It was a Paramecium. He called it "Chausson" (translated slipper) and the term slipper animalcule remained in use as an everyday description for Paramecium throughout the 18th and 19th centuries.

The name "Paramecium" was constructed from the Greek paramekes and means "oblong".
