Charles Chamberland (March 12, 1851 - May 2, 1908) was a French microbiologist from Chilly-le-Vignoble in the department of Jura who worked with Louis Pasteur. In 1884 he developed a type of filtration known today as the Chamberland filter or Chamberland-Pasteur filter, constituting of an unglazed porcelain bar. This filter had pores that were smaller than bacteria, and made it possible to pass a solution containing bacteria through the filter and have them completely removed from the solution. He was also credited for starting a research project that led to the invention of the autoclave device.
