[134][129], In many localities worldwide, streets are named in his honor. Pasteur thought that earthworms might have brought the bacteria to the surface. He performed experiments that showed that, without contamination, microorganisms could not develop. [9] Pasteur made significant discoveries in chemistry, most notably on the molecular basis for the asymmetry of certain crystals and racemization. [44][45], According to his son-in-law, René Vallery-Radot, in August 1857 Pasteur sent a paper about lactic acid fermentation to the Société des Sciences de Lille, but the paper was read three months later. [142] According to both Pasteur Vallery-Radot and Maurice Vallery-Radot, the following well-known quotation attributed to Pasteur is apocryphal:[143] "The more I know, the more nearly is my faith that of the Breton peasant. [86] In his papers published between 1878 and 1880, Pasteur only mentioned Koch's work in a footnote.

[104][105], However, Béchamp was on the losing side, as the BMJ obituary remarked: His name was "associated with bygone controversies as to priority which it would be unprofitable to recall". He did not have any experience in medical practice, and more importantly, lacked a medical license. [33], In 1857, he moved to Paris as the director of scientific studies at the École Normale Supérieure where he took control from 1858 to 1867 and introduced a series of reforms to improve the standard of scientific work.

[52], In the early 19th century, Agostino Bassi had shown that muscardine was caused by a fungus that infected silkworms. He is regarded as one of the three main founders of bacteriology, together with Ferdinand Cohn and Robert Koch, and has been called a "father of bacteriology"[5] and the "father of microbiology"[6][7][page needed], though the latter appelation has also been applied to Antonie van Leeuwenhoek. [131] He was awarded the Cameron Prize for Therapeutics of the University of Edinburgh in 1889. On his return, the month-old cultures made the chickens unwell, but instead of the infections being fatal, as they usually were, the chickens recovered completely. In 1867, he became the chair of organic chemistry at the Sorbonne,[35] but he later gave up the position because of poor health. Teste-toi.

[68][64] Francesco Redi and Lazzaro Spallanzani had provided some evidence against spontaneous generation in the 17th and 18th centuries, respectively.
