The Experiments of Louis Pasteur. Pasteur was the first to experimentally demonstrate that disease was caused by microorganisms in the environment rather than the air itself as proposed by the dominant theory at the time (Miasma theory).

How did Robert Koch contribute to the germ theory?

The germ theory also led to the postulation of germ theory of disease and protection. It was recognised that the immune system had two parts which provided protection from certain types of pathogens. It was Robert Koch who postulated that a specific kind of organism causes a particular type of disease.

What was Louis Pasteur’s germ theory?
