Louis Pasteur
In the 19th century Louis Pasteur's work established the germ theory of disease, proving that microorganisms cause fermentation and sickness, which led to the development of pasteurization, aseptic techniques in medicine, and effective vaccines for diseases such as rabies. (Painting by Albert Edelfelt, 1885.)
Louis and Marie Pasteur had five children together. Tragically, only two of their children survived into adulthood.12
