Louis_Pasteur
Louis Pasteur ( pron.: / ˈ l uː i p æ ˈ s t ɜr / , French: [lwi pastœʁ] ; December 27, 1822 – September 28, 1895) was a French chemist and microbiologist who was one of the most important founders of medical microbiology . He is remembered for his remarkable breakthroughs in the causes and preventions of diseases. His discoveries reduced mortality from puerperal fever , and he created the first vaccines for rabies and anthrax . His experiments supported the germ theory of disease . He was best known to the general public for inventing a method to treat milk and wine in order to prevent it from causing sickness, a process that came to be called pasteurization . He is regarded as one of the three main founders of microbiology , together with Ferdinand Cohn and Robert Koch .Rudolf Virchow
(13 de octubre de 1821 , Schivelbein , Pomerania , Prusia - 5 de septiembre de 1902 , Berlín ) fue un médico alemán considerado como uno de los más prominentes patólogos del siglo XIX . Además de por su labor científica también se le reconoce como estadista, al haber ocupado diversos cargos públicos. Le fue concedida la Medalla Copley en 1892 . Fue nominado al Premio Nobel de Medicina en tres ocasiones, sin resultado.

Fresnel studied the behaviour of light both theoretically and experimentally. He is perhaps best known as the inventor of the Fresnel lens , first adopted in lighthouses while he was a French commissioner of lighthouses, and found in many applications today. His Fresnel equations on waves and reflectivity also form the basis for many applications in computer graphics today - for instance, the rendering of water . [ edit ] Biography Fresnel was the son of an architect, born at Broglie ( Eure ).
