59 After graduation he worked as a physician in different provincial towns. In his spare time, Robert Koch began researching into __________________: the disease regularly took the lives of both animals and humans – but the cause was completely unknown. Finally, in 1876, Koch proved that anthrax is triggered by a single pathogen. He did his re- search in a __________________________ at his home in Wollstein. In 1880 he moved with ______________________ to Berlin. On 24 March 1882 he gave a lecture on the tuberculosis pathogen at the Berlin Institute for Physiology and became world famous overnight. In the 19th cen- tury, tuberculosis was a widespread dis- ease. About a seventh of the population of Germany died of the disease, known as the white plague. For his discovery of the tuberculosis bacterium Robert Koch received _______________________________ in 1905. Like many scientists at the time, Robert Koch also investigated chole- ra. At the end of 1883, Koch and a team of researchers travelled to Calcut- ta in India to _________________________. There, at the beginning of 1884, he managed to _____________________________________. Even though Robert Koch was hailed as the discoverer of the cholera pathogen during his lifetime, he did not deserve all the credit. The Italian anatomist, Filippo Pacini, had already seen and described the pathogen under a mi- croscope back in 1854 – work that found little resonance in Germany at the time and that Koch was unaware of. Thanks to his knowledge on the spread of cholera and the appropriate hygienic methods, Koch helped to ___________________________________________ in Hamburg in 1892. Koch also searched for ways of preventing infectious diseases. His dream of discovering a therapeutic agent or even a vaccine against tuber- culosis, however, did not come true. He developed the remedy called ‗tu- berculin‘ – a mixture of components of devitalised tubercle bacteria, but it proved to be ineffective.
