anniversary of the discovery
of the TB Bacillus by Robert Koch, who on 24 March 1882
announced to the Berlin Physiological Society that he had
discovered the cause of tuberculosis, for which he in 1905
received the Nobel Prize in Physiology and Medicine.
Background composed of
the portrait of Robert Koch, who in 1882 discovered the TB
Bacillus which causes tuberculosis, and which appears six
times, each with an overlay in a different colour, varying
from green to blue. In the foreground is a red Patriarchal
Cross, also known as a Lorraine Cross, i.e. a Latin Cross
with an additional −yet shorter− vertical bar, called
titulus (piece of wood on a cross which displayed an
inscription) and situated above the single vertical bar of a
Latin Cross, which since 1902 is the logo of the Lung
Association, symbolizing the crusade against tuberculosis.
