The invention that allowed viruses to be discovered at all was the Chamberland-Pasteur filter. This was developed in 1884 in Paris by Charles Chamberland, who worked with Louis Pasteur. It consisted of unglazed porcelain “candles”, with pore sizes of 0.1 – 1 micron (100 - 1000 nm), which could be used to completely remove all bacteria or other cells known at the time from a liquid suspension. Though this simple invention essentially enabled the establishment of a whole new science – virology - the continued development of the discipline required a string of technical developments, which we will highlight.
