Data de falecimento: 28. Setembro 1895

Louis Pasteur foi um cientista francês, cujas descobertas tiveram enorme importância na história da química e da medicina. É reconhecido pelas suas notáveis descobertas das causas e prevenções de doenças. Entre seus feitos mais notáveis podem-se citar a redução da mortalidade e a criação da primeira vacina contra a raiva . As suas experiências deram fundamento para a teoria microbiológica da doença. Foi mais conhecido do público em geral por inventar um método para impedir que leite e vinho causem doenças, um processo que veio a ser chamado pasteurização, em homenagem ao seu sobrenome.Pasteur é considerado um dos três principais fundadores da microbiologia, juntamente com Ferdinand Cohn e Robert Koch. Também fez muitas descobertas no campo da química, principalmente a base molecular para a assimetria de certos cristais. O seu corpo está enterrado sob o Instituto Pasteur em Paris, numa tumba decorada por mosaicos em estilo bizantino que lembram os seus feitos.

„How do you know that in ten thousand years, one will not consider it more likely that matter has emerged from life?“

—  Louis Pasteur

Partially quoted in René Dubos, Louis Pasteur: Free Lance of Science, Da Capo Press, Inc., 1950. p 396.
Original in French: «La génération spontanée, je la cherche sans la découvrir depuis vingt ans. Non, je ne la juge pas impossible. Mais quoi donc vous autorise à vouloir qu'elle ait été l'origine de la vie? Vous placez la matière avant la vie et vous faites la matière existante de toute éternité. Qui vous dit que, le progrès incessant de la science n'obligera pas les savants, qui vivront dans un siècle, dans mille ans, dans dix mille ans... à affirmer que la vie a été de toute éternité et non la matière.? Vous passez de la matière à la vie parce que votre intelligence actuelle, si bornée par rapport à ce que sera l'intelligence des naturalistes futurs, vous dit qu'elle ne peut comprendre autrement les choses. Qui m'assure que dans dix mille ans on ne considérera pas que c'est de la vie qu'on croira impossible de ne pas passer à la matière? Si vous voulez être au nombre des esprits scientifiques, s, qui seuls comptent, il faut vous débarrasser des idées et des raisonnements a priori et vous en tenir aux déductions nécessaires des faits établis et ne pas accorder plus de confiance qu'il ne faut aux déductions de pures hypothèses." (Pasteur et la philosophie,Patrice Pinet, Editions L'Harmattan, p. 63.
Contexto: I have been looking for spontaneous generation for twenty years without discovering it. No, I do not judge it impossible. But what allows you to make it the origin of life? You place matter before life and you decide that matter has existed for all eternity. How do you know that the incessant progress of science will not compel scientists to consider that life has existed during eternity, and not matter? You pass from matter to life because your intelligence of today cannot conceive things otherwise. How do you know that in ten thousand years, one will not consider it more likely that matter has emerged from life? You move from matter to life because your current intelligence, so limited compared to what will be the future intelligence of the naturalist, tells you that things cannot be understood otherwise. If you want to be among the scientific minds, what only counts is that you will have to get rid of a priori reasoning and ideas, and you will have to do necessary deductions not giving more confidence than we should to deductions from wild speculation.

„The human spirit, driven by an invincible force, will never cease to ask: What is beyond?“

—  Louis Pasteur

Contexto: The human spirit, driven by an invincible force, will never cease to ask: What is beyond? Does he want to stop either in time or in space? Since the point at which he has reigned is only a finite magnitude, greater only than all those who have preceded him, he has scarcely begun to think of it as the implacable question and always without being able to silence his curiosity. There is nothing to answer: there are spaces, times or magnitudes without limits. No one understands these words. <!-- He who proclaims the existence of the infinite, and no one can escape from it accumulates in this affirmation more supernatural than there is in all the miracles of all religions; for the notion of the infinite has the double character of imposing itself and of being incomprehensible.

„Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.“

—  Louis Pasteur

As quoted in Louis Pasteur, Free Lance of Science (1960) by René Jules Dubos, Ch. 3 "Pasteur in Action"
As quoted in Louis Pasteur, Free Lance of Science (1960) by René Jules Dubos, Ch. 3 "Pasteur in Action"
Contexto: Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world. Science is the highest personification of the nation because that nation will remain the first which carries the furthest the works of thought and intelligence.
