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.
Arthur Arnold Osman
Arthur Arnold Osman (24 May 1893 – 20 April 1972) was a British nephrologist. Osman was one of the first physicians to specialize entirely in the management of renal disorders; the first to recognize that nephrology needed to become a specialty (1930s); published profusely; the first physician to style himself a ‘nephrologist’ (1945); founded the first nephrological society in the world, the Renal Association (1950); and organized the first international meeting devoted entirely to the kidney and its diseases (1953)
