Extractions: After studies in The Netherlands, he worked briefly under August Kekule at Bonn and then in the Paris laboratory of Charles-Adolphe Wurtz, where he met Joseph-Achille Le Bel. In 1874 he and Le Bel, independently of each other, announced a concept that proved to be the cornerstone in the study of the three-dimensional structure (stereochemistry) of organic compounds: the four chemical bonds that carbon can form are directed to the corners of a tetrahedron. This concept helped explain the property of optical rotation.

Extractions: In 1869 he entered the Polytechnic School at Delft and obtained his technology diploma in 1871. His decision to follow a purely scientific career, however, came soon afterwards during vacation-work at a sugar factory when he anticipated for himself a dreary profession as a technologist. After having spent a year at Leiden In 1876 he became lecturer at the Veterinary College at Utrecht, but left this post for a similar position at the University of Amsterdam the following year. In 1878 came his appointment as Professor of Chemistry, Mineralogy, and Geology at the same university. After having occupied this chair for 18 years he accepted an invitation to go to Berlin as Honorary Professor, connected with a membership of the Royal Prussian Academy of Sciences. The principal reason for this change was the fact that he was overburdened with obligations to give elementary lectures and to examine large numbers of students, including even those for medical propaedeutics, leaving him with too little time to do his own research work. He was an ardent advocate for the creation of a special class of scientific workers. At his new post he remained till the end of his life.

http://www.nobel.se/chemistry/laureates/1901/press.html

Extractions: With regard to atomic theory van 't Hoff, following an idea put forward by Pasteur, advanced the hypothesis that the elementary atoms have attachment points geometrically oriented in space - a hypothesis which in so far as carbon compounds are concerned led to the theory of the asymmetry of carbon atoms and to the founding of stereochemistry. By applying these simple principles, which were originally borrowed from mechanics and thermodynamics, van 't Hoff became one of the founders of chemical dynamics. His researches have been a substantial factor in bringing about the magnificent advances in physical chemistry, in which field his discoveries match the great contributions which other investigators, including those in our country, have made in the field of electrochemistry and in the theory of chemical reaction. This has opened up great prospects for scientific research. On the other hand, the investigations on the state of substances in solutions have had and will continue to have the greatest practical consequences - consequences whose benefit to mankind can best be appreciated if we remember that chemical reactions occur predominantly in solutions and that the vital functions of living organisms are maintained by metabolic processes which take place in solutions.

Extractions: volume 9, p. 445-454 (September 1874) [Reader's Note; All figures are in one 44K file at the end of the text.] I desire to introduce some remarks which may lead to discussion and hope to avail myself of the discussion to give my ideas more definiteness and breadth. Since the starting point for the following communication is found in the chemistry of the carbon compounds, I shall for the present do nothing more than state the points having reference to it. It appears more and more that the present constitutional formulas are incapable of explaining certain cases of isomerism; the reason for this is perhaps the fact that we need a more definite statement about the actual positions of the atoms. If we suppose that the atoms lie in a plane, as for example with isobutyl alcohol (Figure I) where the four affinities are represented by four lines in this plane occupying two directions perpendicular to one another, then methane (CH

Extractions: Biological Laboratories, Harvard University, Cambridge, MA 02138 Journal of Chemical Education 23, 8 (August 1986) Editor's Note: Nobel laureate George Wald is Professor Emeritus of Biology at Harvard University and spent many summers in research at the Marine Biological Laboratories, Woods Hole, Massachusetts. Portions of this essay originally appeared in a somewhat different form in the September 17, 1982 edition of Science. When W. J. V. Osterhout (1871-1964) was a member emeritus of the Rockefeller Institute, he told this story to me during one of my visits to him and his wife and co-worker Marion (Ikky) Irwin, in their apartment at the Marine Biological Laboratories in Woods Hole. I begged him to write it out, for I thought it too interesting and important to be lost, but he never did. I shall tell it first as he told it to me, for I think he had it from the source, as we shall see. Then I will authenticate it, as I now can do. I wish to dedicate this essay to his memory. One day in Amsterdam, Jacobus Henricus van't Hoff (1852-1911), the "father of physical chemistry", was walking down the street from his laboratory when he encountered his fellow professor, the botanist Hugo de Vries, out walking with his wife. Having met, they went on together, whereupon de Vries ventured, "The other day I had a letter from Pfeffer" [Wilhelm Pfeffer (1845-1920), the botanist who pioneered the use of semipermeable membranes to measure osmotic pressure]. When van't Hoff inquired in the desultory Dutch equivalent of "Oh, yeah? What's he up to?" de Vries replied, "He says he's measuring the effect of temperature on osmotic pressure." "What does he get?" asked van't Hoff. "Well," replied de Vries, "he writes that for each degree rise in temperature the osmotic pressure goes up by about 1/270."

It is generally regarded as the supreme commendation in the world today. The prizes were instituted by the final will of Alfred Nobel, a Swedish industrialist, and the inventor of dynamite. He signed his will at the Swedish-Norwegian Club in Paris on November 27, 1895. He was shocked to see how his invention was used for destructive purposes and wanted the prizes to be awarded to those who served mankind well. Click the link for more information. in Chemistry Chemistry is the scientific study of the structure, properties, composition, and reactions of chemical elements and compounds. The atomic theory is basic to chemistry. The theory states that all matter is composed of a set of very small units called atoms. One of the very first laws to be discovered leading to the establishment of chemistry as a science is the Law of Conservation of Mass. This law states there is no detectable change in the quantity of matter during an ordinary chemical reaction. (Modern physics now shows that it is actually energy that is conserved, and that energy and mass are related)
