In the 19th century, the French scientist Louis Pasteur made the groundbreaking discovery that the earth is full of microscopically small organisms. Pasteur also found out that some of them cause serious disease as for example diphtheria, pest, typhoid, yellow fever, cholera, tuberculosis, influenza and rabies. It was a revolutionary discovery for that time. Pasteur investigated how those diseases are transmitted and what hygiene has to do with it. (iTunes)
