ReferenceBrock (1961)
NotesEnglish translation in Brock, 1961. While not the first to use solid medium for isolating pure cultures, Koch made the technique more useful by combining nutrient broth and gelatin, making a medium that (unlike sliced potato) would support a great variety of bacteria, while at the same time providing the solidity needed for picking out discrete colonies. Koch also made a notable demonstration at the Intl. Med. Cong. in London.
