Plant anatomy
It was in the late 1600s that plant anatomy became refined into a modern science. Italian doctor and microscopist, Marcello Malpighi, was one of the two founders of plant anatomy. In 1671 he published his "Anatomia Plantarum", the first major advance in plant physiogamy since Aristotle. The other founder was the British doctor Nehemiah Grew. He published "An Idea of a Philosophical History of Plants" in 1672 and "The Anatomy of Plants" in 1682. Grew is credited with the recognition of plant cells, although he called them 'vesicles' and 'bladders'. He correctly identified and described the sexual organs of plants (flowers) and their parts.
Robert Koch
Heinrich Hermann Robert Koch (; ; 11 December 1843 – 27 May 1910) was a German physician and microbiologist. As the founder of modern bacteriology, he identified the specific causative agents of tuberculosis, cholera, and anthrax and gave experimental support for the concept of infectious disease, which included experiments on humans and animals. Koch created and improved laboratory technologies and techniques in the field of microbiology, and made key discoveries in public health. His research led to the creation of Koch's postulates, a series of four generalized principles linking specific microorganisms to specific diseases that remain today the "gold standard" in medical microbiology. For his research on tuberculosis, Koch received the Nobel Prize in Physiology or Medicine in 1905. The Robert Koch Institute is named in his honor.
