	Jacobus Henricus van 't Hoff - Wikipedia, the free encyclopedia
		Jacobus Henricus van 't Hoff (August 30, 1852 - March 1, 1911) was a Dutch physical and organic chemist and the winner of the inaugural Nobel Prize in chemistry.
		Van 't Hoff became a lecturer in chemistry and physics at the Veterinary College in Utrecht.
		Van 't Hoff died at the age of 58, on March 1, 1911, at Steglitz near Berlin.

	J.H. van 't Hoff, 100 jaar Nobelprijs: 1901-2001
		Van 't Hoff ontdekte in de resultaten van anderen dat er bij koolstofatomen die door verschillende groepen omringd werden er minder verschillende vormen (isomeren) experimenteel konden worden aangetoond dan er op papier konden worden getekend.
		Van 't Hoff stelde dat slechts in dit geval er meer dan één isomeer van een verbinding kon bestaan, wat direct een verklaring was voor de optische activiteit van deze verbindingen.
		Van 't Hoff is natuurlijk in de eerste plaats belangrijk als chemicus vanwege de ontdekkingen die hij gedaan heeft.

	Media Review
		The title for Chapter 1, “Introduction: ‘Van ’t Hoff’s Gold Mines’” (10 pp, the shortest chapter), is taken from a characterization of Van ’t Hoff’s theory as “gold mines that have gone entirely unnoticed” [6].
		Also, because few chemists were fluent in Dutch, and because most of them learned of Van ’t Hoff’s proposals from either the French version (1875) [8] or the German version (1877) [9], the chapter closely examines the evolution from the Dutch pamphlet to the German version.

		The summer-house for J. Verloop (1914) and the country villa for A. Henny (1915–19), both at Huis ter Heide, reflect his admiration for Wright, and the latter, nicknamed the ‘Concrete villa’ for its inventive use of concrete-frame construction, established van ’t Hoff’s reputation.
		Van ’t Hoff became a member of the Communist Party in 1918–19; he initiated an exchange programme with Soviet artists and worked on designs for blocks of flats and mass construction, but none of these projects was realized.
		For van ’t Hoff the relation between the artistic avant-garde and the proletarian revolution was self-evident, but in 1919, when the international revolution failed to materialize, he withdrew from De Stijl and eventually from artistic life altogether.

		Van't Hoff had studied with Kekulé in Bonn for several terms in 1872-73, so there is no doubt that he was familiar with Kekulé's ball-and-stick lecture models of tetrahedral carbon.
		Here are his drawings of the two diacids (fumaric and maleic acids, known at the time) from replacing one H on each carbon of ethylene with COOH.
		While van't Hoff did no experimental work himself to support his stereochemical theory, he cited many examples of previously confusing observations that were in agreement with predictions of his theory.

		For weak electrolytes this is still believed the case, but modifications (by Peter J. Debye and Erich Hückel) were found necessary to account for the behavior of strong electrolytes.
		The dissertation was not very impressive to the professors at Uppsala, but Arrhenius sent it to a number of scientists in Europe who were developing the new science of physical chemistry, such as Rudolf Clausius, Wilhelm Ostwald, and J. van 't Hoff.
		Arrhenius declined, however, as he preferred to stay in Sweden for a while (his father was very ill and would die in 1885) and had gotten an appointment at Uppsala.

		The reason is that the carbon atom in the centre binds the four different groups H, CH and COOH, which are located at the corners of a tetrahedron.
		The unbroken bonds to NH and COOH indicate that these bonds are in the plane of the paper, whereas the fl wedge shaped bond and the broken wedge shaped bond show that they are directed upwards and downwards respectively in relation to the plane of the paper.
		It was the Dutch chemist J. van 't Hoff and the French chemist J. Le Bel who, independently of each other in 1874, discovered this tetrahedral arrangement of the groups around the central carbon atom.

		The solution Avogadro suggested is that the smallest particle of an element can sometimes consist of twoatoms joined together in a molecule, a term he invented for the new particle.
