Germ History Made Simple
Microbes are tiny organisms that cause diseases such as; strep throat, ear infections, and pneumonia in people. Microbes were first discovered in the late 1600s, but the idea that these tiny organisms could cause these diseases did not develop until the 1800's.

Scientist (Life Span)
Occupation Most Famous Contribution to Science Other Contributions to Science
Robert Hooke (1635-1703)
Scientist/ Inventor Made drawings of individual cells in plants. Made Microscopes to observe
microscopic things
Rudolf Carl Virchow
He pioneered the modern concept of pathological processes by his application of the cell theory to explain the effects of disease in the organs and tissues of the body. He emphasized that diseases arose, not in organs or tissues in general, but primarily in their individual cells.
Robert Koch
He invented methods to purify the bacillus from blood samples and grow pure cultures Identified microbe that caused “Anthrax” which was killing thousands of cows.
Florence Nightingale (1820-1910)
Wartime Nurse
Developed a form of the pie chart now known as the polar area diagram, or occasionally the Nightingale rose diagram. made a comprehensive statistical study of sanitation.
Joseph Lister
Successfully introduced carbolic acid (now known as phenol) to sterilise surgical instruments and to clean wounds, which led to reducing post-operative infections and made surgery safer for patients. Promoted the idea of sterile surgery while working at the Glasgow Royal Infirmary.
B. Explain the 3 main components of the Cell Theory and know them for Friday's Quiz!.
The theory says that new cells are formed from other existing cells, and that the cell is a fundamental unit of structure, function and organization in all living organisms.
C. Describe how the contributions of Louis Pasteur made foods and beverages safer for people and go on to explain how this revolutionary process continues in our lives today.
He began to study fermentation and how it related to alcoholic drinks. His research led to the process of pasteurization* of milk to kill viruses and harmful bacteria. The milk is not heated to the boiling point which would change the flavor, but is heated to a temperature sufficient to kill the bacteria which would cause it spoil easily or cause disease. It is then chilled and must be kept cold until used.
He named the new science bacteriology* and suggested a new theory, The Germ Theory of Disease. He believed that diseases were caused by germs attacking the body from the outside.
He made food and beverages safer for people everywhere.
D. Briefly explain the term Germ Theory of Disease.
The germ theory of disease, also called the pathogenic theory of medicine, is a theory that proposes that microorganisms are the cause of many diseases.
