from the German wikipedia site Table of contents 1	Life 2	factories 3	literature 4	Web links Life Heinrich Ludwig Buff was born in 1828 as the son of Oberbergrat Ludwig Carl Christian Buff. Buff was trained as a pharmacist in Siegen before he studied chemistry in Gießen in 1851 and then became Liebig's assistant in Munich and later in London, successively to John Stenhouse and August Wilhelm von Hofmann.

His first study on nitrogen iron (1852) was followed in 1855 and 1856 by treatises on sulfur cyanethylene and the constitution of hydrocarbons and their derivatives: works of importance in that the ideas about valence and atomic storage that were just emerging at the time were expressed in them. He converted sulfur cyanethylene into disulfeholic acid, recognized the bivalence of the radical ethylene 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 Kraut's laboratory at the Hanover Polytechnic School and gave lectures there. Buff received his doctorate in Göttingen in 1863 with a dissertation on fats and the production of fatty acids and glycerol and completed his habilitation as a private lecturer at the same university.

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

The majority of papers published during his second scientific period dealt with the idea that the atoms of many elements can actuate a changing 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 creation and decay. The works mostly appeared in the Annals of Chemistry and the reports of the German Chemical Society.
