amount of valuable work in connection with tuberculosis throughout 
the civilized world, but the relative importance of infection from one 
another through sputum and from bovines through dairy produce 
is still an open question, and will not be settled for many years to 
come. 
Before closing this sketch of his life work, it remains to add a few 
words upon Koch as a teacher. In 1885 he removed from the health 
department and became a professor in the faculty of medicine and 
director of the new hygiene institute, attached to the University of 
Berlin. Here, with the help of his assistants, numbers of those who 
later became leading bacteriologists in all countries were trained in his 
methods and endowed with some portion of his enthusiasm and earn- 
estness. The admiration with which he was regarded by his pupils, 
and the absolute faith which he inspired, amounted in many cases to 
actual worship, and afford further evidence of the essential greatness 
of the man. 
Amongst the numerous honors conferred upon him by scientific and 
academic bodies throughout the civilized world was the foreign mem- 
bership of the Royal Society, to which he was elected in 1897. 
There have no doubt been many discoverers as great as Koch, but 
it must be seldom that one has been so individually associated with 
the development of a science. Bacteriology has to so great an extent 
grown up around Koch that the title “Father of Bacteriology” has 
been conferred upon him by his admiring compatriots.
