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.
In September 2001, letters containing anthrax spores were mailed to several news media offices and two U.S. Senators, killing five people and infecting 17 others. Of those infected, 11 developed cutaneous anthrax, while 11 developed inhalation anthrax. 20 of the 22 infected worked at a site where contaminated mail was handled or received. [7]
A rare disease, human anthrax is most common in Africa and central and southern Asia. [11] It also occurs more regularly in Southern Europe than elsewhere on the continent and is uncommon in Northern Europe and North America. [ 12 ]
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 ]
As the interwar period continued, the United States did not emphasize biological weapons development or research. [1] While the U.S. was spending very little time on biological weapons research, its future allies and enemies in the upcoming second World War were researching the potential of biological weapons as early as 1933.

In 1876, German biologist Robert Koch discovered that a bacterium (Bacillus anthracis) was the causative pathogen of anthrax, which became the first demonstration that a specific bacterium caused a specific disease and the first direct evidence of germ theory of diseases.

Anthrax weaponization is the development and deployment of the bacterium Bacillus anthracis or, more commonly, its spore (referred to as anthrax), as a biological weapon. As a biological weapon, anthrax has been used in biowarfare and bioterrorism since 1914. [ 1 ]
