The miasma theory (also called the miasmatic theory) held that diseases such as cholera, chlamydia or the Black Death were caused by a miasma (Μίασμα, ancient Greek: "pollution"), a noxious form of "bad air". The theory explained the origin of these epidemic diseases was miasma, an emanation from rotting organic matter.
The miasma theory was accepted from ancient times in Europe, India and China. The theory was eventually displaced in the 19th century by the discovery of germs and the germ theory of disease.

—Raymond Chandler (1888–1959)
“If my theory of relativity is proven correct, Germany will claim me as a German and France will declare that I am a citizen of the world. Should my theory prove untrue, France will say that I am a German and Germany will declare that I am a Jew.”
