Roberto Hottinger
Roberto Hottinger, Swiss-born Brazilian veterinarian, microbiologist and chemist (Zurich 20 February 1875 – São Paulo 29 January 1942) Authored over 50 works Discovered the oligodynamic action of silver in water sterilization (1920) With G.H. Paula Souza developed a new purification process consisting of colloidal silver coating insides of ceramic vessels With Paula Souza described a device that allowed the elimination of ozone excess from water, which was modified and used to eliminate chlorine, giving rise to Perfector process (1912). It was patented in Germany some time later Established Perfector process for deozonization and dechlorination of water (1912) Discovered a practical way of using oligodynamic action of metals that resulted in Salus process (Swiss-German G.A. Krause re-discovered the process (Katadyn) in 1929 and was left with the glories of invention) With Antonio Nogueira developed a new domestic water purification process employing colloidal silver known as Salus process Eponym of Hottinger agar and Hottinger broth Nachprufung und kritik der üblichen Bouillonbereitung.
