Jacobus Henricus van 't Hoff

Biography

He was born in Rotterdam, the son of a medical doctor. From a young age he was interested in science and nature; he frequently took part in botanical excursions, and his receptiveness for philosophy and his predilection for poetry were already apparent in his early school years. (Lord Byron was his idol.) Against the wishes of his father, he went to study C. A. Wurtz), finally receiving his doctorate at the University of Utrecht in 1874. 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).

Career

Contributions to chemistry

Before receiving his doctorate, van 't Hoff had already published the first of his important contributions to stereochemistry). 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 the geometry of science in his book La chimie dans l'éspace in 1874. At the time, his theory was considered an extraordinary claim in science, and was criticized strongly by the scientific community. One such critic was the renown editor of the German Journal für praktische Chemie, Adolf Kolbe, who stated:

"A Dr. H. van ’t Hoff of the Veterinary School at Utrecht has no liking, apparently, for exact chemical investigation. 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 fly."

However, van 't Hoff's work was revolutionary, and became indispensable in science.

In 1884 van 't Hoff published his research on chemical kinetics, naming it Études de Dynamique chimique ("Studies in Chemical Dynamics"), in which he described a new method for determining the Wilhelm Ostwald founded an influential scientific magazine named Zeitschrift für physikalische Chemie ("Journal of Physical Chemistry").

The Nobel Prize in Chemistry

  Van 't Hoff became a lecturer in chemistry and physics at the Veterinary College in Utrecht. He then became a professor of gases.

Honours and awards

In 1885 he was appointed member of the Royal Netherlands Academy of Sciences. Other distinctions included the honorary doctorates of Harvard and Yale 1901, Victoria University, Manchester 1903, Heidelberg 1908; the Davy Medal of the Royal Society 1893 (along with Le Bel), Helmholtz Medal of the Prussian Academy of Sciences 1911; he was also appointed Chevalier de la Legion d'Honneur 1894, Senator der Kaiser-Wilhelm-Gesellschaft (1911). Van 't Hoff was also honorary member of the British Chemical Society in London, the Royal Academy of Sciences, in Göttingen 1892, American Chemical Society 1898, and the Académie des Sciences, in Paris 1905.

He was indeed a prominent scientist of its time. Of his numerous distinctions, he regarded his winning of the first Nobel Prize in Chemistry as the culmination of his career.

Van 't Hoff died at the age of 58, on March 1, 1911, at Steglitz near Berlin from tuberculosis.
