Heinrich Hermann Robert Koch (/ k ɒ x / KOKH; [1] [2] German: [ˈʁoːbɛʁt ˈkɔx] ⓘ; 11 December 1843 – 27 May 1910) was a German physician and microbiologist.As the discoverer of the specific causative agents of deadly infectious diseases including tuberculosis, cholera and anthrax, he is regarded as one of the main founders of modern bacteriology.
Although Koch arguably made the greatest theoretical contribution to understanding anthrax, other researchers were more concerned with the practical questions of how to prevent the disease. In Britain, where anthrax affected workers in the wool, worsted , hides , and tanning industries, it was viewed with fear.
The Fra Mauro map, completed around 1459, is a map of the then-known world. Following the standard practice at that time, south is at the top. The map was said by Giovanni Battista Ramusio to have been partially based on the one brought from Cathay by Marco Polo. This is a chronology of the early European exploration of Asia. [1]
Koch took his research into a new direction—applied research—to develop a tuberculosis treatment and use the profits to found his own research institute, autonomous from government. [17] In 1890 Koch introduced the intended drug, tuberculin , but it soon proved ineffective, and accounts of deaths followed in news press. [ 18 ]

The species name anthracis is from the Greek anthrax (ἄνθραξ), meaning "coal" and referring to the most common form of the disease, cutaneous anthrax, in which large, black skin lesions are formed. Throughout the 19th century, Anthrax was an infection that involved several very important medical developments.
Five countries in East and southern Africa are in the middle of outbreaks of the anthrax disease, with more than 1,100 suspected cases and 20 deaths this year, the World Health Organization said ...
As Koch continued to do this, the mice still died, and the anthrax rods changed shape upon his evaluation. The elongated rods appeared to be in the process of reproducing. [64] Koch then took the eye of an ox and placed the anthrax bacteria within it. He predicted the bacteria was alive and this was proven to be true when the bacteria multiplied.
