On December 11, 1843, scientist Robert Koch was born, doctor who discovered the tuberculosis bacillus, winner of the Nobel Prize in 1905 (d. May 27, 1910).

Robert Koch was born in the small town of Clausthal, Germany. He taught himself to read and write, and at school he achieved excellent results in mathematics.

At the age of 19, Koch entered the University of Göttingen to study natural sciences, but after two semesters, he decided to embrace medicine. During his studies he began to collaborate with the distinguished specialist in anatomy Jacob Henle who launched the theory of contagion, according to which wounds are infected by microbes. Already in the sixth semester, Koch was coordinating research at the University’s Institute of Physiology. The fact that he graduated from the university with the highest distinction already seems self-evident.

In the years 1872-1880 he was an officer of the Wollstein Medical District; during this period he takes the first steps in the development of scientific research on the organisms that cause infections. Anthrax at that time was very widespread in the district of Wollstein, and Koch without any financial or scientific help aims to discover as much as possible about this scourge. The laboratory was his home, as equipment he had a microscope given by his wife, and the instruments were procured by himself. The anthrax bacillus was discovered by Pollender, Rayer and Davaine, but Koch aims to prove that this bacillus is actually the agent that produces the disease. For this purpose, he inoculates mice with extracts from the spleen of sick animals, and finds that they die, while the mice in the group injected with extracts from healthy animals live. The experiment confirms a fact that was suspected, namely that the blood of infected animals is able to transfer the disease to healthy animals. Koch is not satisfied with this result and goes further, demonstrating that bacilli retain their virulence even in the absence of any animal organism.

Koch established the bacterial cause of several infectious diseases and discovered the microorganisms that cause anthrax (1876), wound infection (1878), tuberculosis (1882), conjunctivitis (1883), cholera (1884) and other diseases. He was a professor at the University of Berlin from 1885 to 1891 and head of the Institute of Infectious Diseases (which he also founded) from 1891 to 1904. In the course of his bacteriological research for the German and English governments, he traveled to South Africa, India, Egypt and other countries. On this occasion, he made valuable studies on sleeping sickness, malaria, bubonic plague, leprosy and other diseases. For his contributions to the study of tuberculosis infection, Koch received in 1905 the Nobel Prize for Physiology/Medicine.
