--Louis Pasteur, chemist and bacteriologist (1822-1895)

(26:5.3) But long before reaching Havona, these ascendant children of time have learned to feast upon uncertainty, to fatten upon disappointment, to enthuse over apparent defeat, to invigorate in the presence of difficulties, to exhibit indomitable courage in the face of immensity, and to exercise unconquerable faith when confronted with the challenge of the inexplicable. Long since, the battle cry of these pilgrims became: "In liaison with God, nothing—absolutely nothing—is impossible."

(69:2.5) Labor, the efforts of design, distinguishes man from the beast, whose exertions are largely instinctive. The necessity for labor is man's paramount blessing. The Prince's staff all worked; they did much to ennoble physical labor on Urantia. Adam was a gardener; the God of the Hebrews labored—he was the creator and upholder of all things. The Hebrews were the first tribe to put a supreme premium on industry; they were the first people to decree that "he who does not work shall not eat." But many of the religions of the world reverted to the early ideal of idleness. Jupiter was a reveler, and Buddha became a reflective devotee of leisure.

(140:8.2) Jesus' teaching to trust in the overcare of the heavenly Father was not a blind and passive fatalism. He quoted with approval, on this afternoon, an old Hebrew saying: "He who will not work shall not eat." He pointed to his own experience as sufficient commentary on his teachings. His precepts about trusting the Father must not be adjudged by the social or economic conditions of modern times or any other age. His instruction embraces the ideal principles of living near God in all ages and on all worlds.

    Louis Pasteur was a French biologist, microbiologist and chemist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization. He is remembered for his remarkable breakthroughs in the causes and prevention of diseases, and his discoveries have saved many lives ever since. He reduced mortality from puerperal fever, and created the first vaccines for rabies and anthrax.
    His medical discoveries provided direct support for the germ theory of disease and its application in clinical medicine. He is best known to the general public for his invention of the technique of treating milk and wine to stop bacterial contamination, a process now called pasteurization. He is regarded as one of the three main founders of bacteriology, together with Ferdinand Cohn and Robert Koch, and is popularly known as the "father of microbiology".
    Pasteur was responsible for disproving the doctrine of spontaneous generation. He performed experiments that showed that, without contamination, microorganisms could not develop. Under the auspices of the French Academy of Sciences, he demonstrated that in sterilized and sealed flasks, nothing ever developed; and, conversely, in sterilized but open flasks, microorganisms could grow. Although Pasteur was not the first to propose the germ theory, his experiments indicated its correctness and convinced most of Europe that it was true.
    Today, he is often regarded as one of the fathers of germ theory. Pasteur made significant discoveries in chemistry, most notably on the molecular basis for the asymmetry of certain crystals and racemization. Early in his career, his investigation of tartaric acid resulted in the first resolution of what is now called optical isomers. His work led the way to the current understanding of a fundamental principle in the structure of organic compounds.
    He was the director of the Pasteur Institute, established in 1887, until his death, and his body was interred in a vault beneath the institute. Although Pasteur made groundbreaking experiments, his reputation became associated with various controversies. Historical reassessment of his notebook revealed that he practiced deception to overcome his rivals.
