Robert Koch, the father of modern medical microbiology

Robert Koch was born in Clausthal on December 11, 1843. He was the third child of a total of eleven and showed precocity to learn to read thanks to the daily management of newspapers. Like his father, a mine technician, he also always had a desire and a fondness for traveling, which undoubtedly should have helped him later to know places in remote Africa and India to study diseases and epidemics such as malaria and the plague.
since childhood, Robert Koch felt passion for nature, especially for animals, so when he finished school, always with good grades for his dedication and taste for study, he enrolled at the University of Göttingen to pursue a career in Medicine and there he became interested in Microbiology. Always as a model student, he learned that infectious diseases can be caused by living organisms, bacteria, and from that moment he became an inseparable friend of the microscope.
His first studies focused on the anthrax bacillus, as he witnessed an epidemic that devastated hundreds of cattle. In his small laboratory, Robert Koch conducted several experiments to demonstrate that the anthrax bacillus caused the disease that infected cattle and that these bacteria were able to reproduce even without direct contact with the animal. He invented methods to extract the bacillus from blood samples and make it grow in pure cultures. He also discovered that while he was unable to survive for long periods outside the living being, the bacillus could create endospores that could. These endospores, embedded in the ground, were the cause of the unexplained spontaneous outbreaks of anthrax. Koch published his discoveries in 1876 and was awarded a job at the Imperial Health Office in Berlin in 1880. A year later, in 1881, he promoted the sterilization of surgical instruments by heat. In the scientific environments of the time, the discovery of Koch was really a revelation and meant a revolution as of that moment, since the German doctor did not dispose, much less, of a laboratory equipped for this type of experiments. Thanks to his intuitions, other scholars and later researchers were able to follow his steps and deepen their studies
The German scientist Robert Koch contributed so decisively to the study of diseases that he is considered the father of modern medical microbiology and bacteriology with the famous Louis Pasteur despite the few resources with which he achieved it.

Robert Koch is best remembered for the discovery of the bacteria responsible for tuberculosis (also called Koch's Bacillus), as well as identifying the substance that acts as a remedy for the disease, the so-called tuberculin.
As important as his work in tuberculosis, for which he was awarded the Nobel Prize, are Koch's Postulates, which state that to establish that an organism is the cause of a disease, it must be present in all cases in which the disease is examined and absent in healthy organisms; it must be able to be prepared and maintained in a pure culture; have the ability to produce the original infection after several generations in a crop and, finally, must be able to be inoculated into animals and cultivated again.
