Heinrich Ludwig Buff

from Wikipedia, the free encyclopedia

Heinrich Ludwig Buff (born August 23, 1828 in Siegen , † December 2, 1872 in Prague ) was a German university professor and chemist.

Life

Heinrich Ludwig Buff was born in 1828 as the son of Oberbergrats Ludwig Carl Christian Buff . Buff was trained as a pharmacist in Siegen before he studied chemistry in Gießen in 1851 and then became an assistant to John Stenhouse and August Wilhelm von Hofmann in Munich and later in London .

His first study of nitrogen iron (1852) was followed in 1855 and 1856 by treatises on cyanide sulfur and the constitution of hydrocarbons and their derivatives: works of importance insofar as the ideas about valence and atomic storage that were just emerging were expressed in them. He converted cyanide sulfur into disulfetholic acid, recognized the bivalence of the ethylene radical and tried in vain to obtain the corresponding alcohol.

In 1859 he founded a stearin factory in Osnabrück with great difficulty, so that he was forced to close the factory again in 1861. In the summer of 1863 he worked in Krauts laboratory of the polytechnic school in Hanover and gave lectures there. Buff received his doctorate in Göttingen in 1863 with a dissertation on the fats and production of fatty acids and glycerine and completed his habilitation at the same university as a private lecturer.

In 1867 he gave lectures at the trade museum and later became Hofmann's assistant at the university laboratory. In the autumn of 1869 he was given a professorship in Prague, which was interrupted only two years later due to illness and death.

Most of the work published during his second scientific period was concerned with the idea that the atoms of many elements can operate an alternating valence. With this change, he tried to prove, a change occurs in the filling of space and with it the movement of the molecules, which causes all chemical reactions, the entire cycle of becoming and passing away. Most of the work appeared in the Annalen der Chemie and the reports of the German Chemical Society.
