Against the wishes of his father, van't Hoff chose to study [[chemistry]], first at the [[Delft University of Technology|Delft Polytechnic Institute]], then latter at the [[University of Leiden]]. He then studied in [[Bonn]], Germany with [[Friedrich August Kekulé von Stradonitz|Friedrich Kekulé]] and in Paris with [[Charles-Adolphe Wurtz|C. A. Wurtz]].

In 1878, van 't Hoff married Johanna Francina Mees. They had two daughters, Johanna Francina (b. 1880) and Aleida Jacoba (b. 1882), and two sons, Jacobus Hendricus (b. 1883) and Govert Jacob (b. 1889).

Before he received his doctorate, van 't Hoff had already published the first of his important contributions to the field of [[organic chemistry]]. In 1874 he accounted for the phenomenon of [[optical activity]] by assuming that the [[chemical bond]]s between [[carbon]] [[atom]]s and their neighbors were directed towards the corners of a regular [[tetrahedron]]<ref>http://www.youtube.com/user/periodicvideos#p/u/0/b_L9DcGiXyc</ref>. This three-dimensional structure accounted for the [[isomer]]s found in nature. He shares credit for this idea with the French chemist [[Joseph Le Bel]], who independently came up with the same idea.

Van 't Hoff published his work on [[stereochemistry]] in his book ''La chimie dans l'éspace'', in 1874. At the time, his theory was considered revolutionary, and was strongly pcriticized by the scientific community. One such critic was the renowned editor of the German ''Journal für praktische Chemie'', [[Adolph Kolbe]], who stated:

In 1884, van 't Hoff published his research on chemical kinetics, titled ''Études de Dynamique chimique'' (''"Studies in Chemical Dynamics"''), in which he described a new method for determining the [[Order (chemistry)|order of a reaction]] using [[graphics]], and applied the laws of [[thermodynamics]] to chemical equilibria. He also introduced the modern concept of [[chemical affinity]]. In 1886, he showed a similarity between the behaviour of dilute solutions and gases. In 1887, he and German chemist [[Wilhelm Ostwald]] founded an influential scientific magazine named ''Zeitschrift für physikalische Chemie'' ''("Journal of Physical Chemistry")''. He worked on [[Svante Arrhenius]]'s theory of the dissociation of [[electrolytes]] and in 1889 provided physical justification for the [[Arrhenius equation]]. In 1896, he became professor at the ''Prussian Academy of Science'' in Berlin. His studies of the salt deposits at [[Stassfurt]] were an important contribution to Prussia's chemical industry.

Jacobus Henricus van 't Hoff (30 August 1852 – 1 March 1911) was a Dutch physical and organic chemist and the first winner of the inaugural Nobel Prize in chemistry. His is most well know for research in chemical kinetics, chemical equilibrium, osmotic pressure and stereochemistry. van 't Hoff work in these subjects helped found the discipline of physical chemistry as it is known today.

Biography

van 't Hoff was born in Rotterdam, Netherlands, and was the third of seven children. His father was Jacobus Henricus van 't Hoff, a physician, and his mother was Alida Jacoba Kolff.[1] From a young age he was interested in science and nature, and frequently took part in botanical excursions. In his early school years, he showed a strong interest in poetry and philosophy. He considered Lord Byron to be his idol.

Against the wishes of his father, van 't Hoff chose to study chemistry, first at the Delft Polytechnic Institute, then latter at the University of Leiden. He then studied in Bonn, Germany with Friedrich Kekulé and in Paris with C. A. Wurtz. He received his doctorate under Eduard Mulder at the University of Utrecht in 1874. [2]

In 1878, van 't Hoff married Johanna Francina Mees. They had two daughters, Johanna Francina (b. 1880) and Aleida Jacoba (b. 1882), and two sons, Jacobus Hendricus (b. 1883) and Govert Jacob (b. 1889). van 't Hoff died at the age of 58, on 1 March 1911, at Steglitz near Berlin from tuberculosis.

Career

van 't Hoff in the 1900s.

Before he received his doctorate, van 't Hoff had already published the first of his important contributions to the field of organic chemistry. In 1874 he accounted for the phenomenon of optical activity by assuming that the chemical bonds between carbon atoms and their neighbors were directed towards the corners of a regular tetrahedron[3]. This three-dimensional structure accounted for the isomers found in nature. He shares credit for this idea with the French chemist Joseph Le Bel, who independently came up with the same idea.

van 't Hoff published his work on stereochemistry in his book La chimie dans l'éspace, in 1874. At the time, his theory was considered revolutionary, and was strongly criticized by the scientific community. One such critic was the renowned editor of the German Journal für praktische Chemie, Adolph Kolbe, who stated:

He has considered it more comfortable to mount Pegasus (apparently borrowed from the Veterinary School) and to proclaim in his ‘La chimie dans l’espace’ how the atoms appear to him to be arranged in space, when he is on the chemical Mt. Parnassus which he has reached by bold flight.
