About this work


This type of filter was invented by Charles Chamberland (1851-1908), a French microbiologist and colleague of Louis Pasteur. Chamberland showed that porous materials such as porcelain, when slightly heated, can keep hold of fine particles in suspension. By placing a piece of porcelain in a glass tube he created a sterilisation process for liquids which worked better than contemporary techniques. It was also useful for purifying water. Louis Pasteur (1822-1895) and Chamberland worked together studying chicken cholera and anthrax, two diseases which had had a huge impact on French agriculture, killing large numbers of animals. They used the Chamberland filter in their experiments, which were based on the germ theory of disease. maker: Unknown maker Place made: France
