'Louis Pasteur', 1885. Pasteur (1822-1895), French chemist and biologist at work in his laboratory. Pasteur developed the pasteurisation process which kills pathogens in milk, wine and foods, and he produced vaccines against anthrax and rabies. In 1884 he was appointed Professor of Chemistry at the University of Lille where he researched the reasons why some alcohols turn sour, discovering in the process, that by heating liquid to a certain temperature, the bacteria were killed.
