Milne-Edwards served as a professor at the Muséum national d'Histoire naturelle in Paris and published several important works, including descriptions and classifications of various species.
Hans Krebs (1900-1981) was a distinguished British biochemist of German origin, renowned for his significant contributions to the field of biochemistry, particularly in understanding cellular respiration. He is best known for discovering the urea cycle and the citric acid cycle (also known as the Krebs cycle), both of which are fundamental metabolic pathways in living organisms.
Giovanni Plana (1781–1864) was an Italian astronomer and mathematician, known for his contributions to celestial mechanics and astronomy. He is recognized for his work on the theory of comets and planetary orbits, as well as for his role in the development of astronomical instruments. Plana also made significant contributions to the field of mathematical analysis.
George William Hill (1838-1914) was a prominent British astronomer and mathematician known for his work in celestial mechanics. He is best known for the development of the Hill equations and contributions to the stability of the moon's motion among celestial bodies. His work laid important groundwork for the study of the motion of satellites and the mathematical principles governing their orbits.
George Shuckburgh-Evelyn was an English politician, scientist, and landowner in the late 18th and early 19th centuries. He was born in 1751 and is primarily remembered for his contributions to various scientific fields, including botany and meteorology, as well as his involvement in local government.
