Eduard Buchner (20 May 1860 – 13 August 1917) was a Germanmarker chemist and zymologist, the winner of the 1907 Nobel Prize in Chemistry for his work on fermentation.


Early years

Buchner was born in Munichmarker to a physician and Doctor Extraordinary of Forensic Medicine. In 1884, he began studies of chemistry with Adolf von Baeyer and of botany with Professor C. von Naegeli, at the Botanic Institute in Munich. After a period working with Otto Fischer in Erlangenmarker, Buchner was awarded a doctorate from the University of Munichmarker in 1888.


The experiment for which Buchner won the Nobel Prize consisted of producing a cell-free extract of yeast cells and showing that this "press juice" could ferment sugar. This dealt yet another blow to vitalism by showing that the presence of living yeast cells was not needed for fermentation. The cell-free extract was produced by combining dry yeast cells, quartz and kieselguhr and then pulverizing the yeast cells with a pestle and mortar. This mixture would then become moist as the yeast cells' contents would come out of the cells. Once this step was done, the moist mixture would be put through a press and the resulting "press juice" had glucose, fructose, or maltose added and carbon dioxide was seen to evolve, sometimes for days. Microscopic investigation revealed no living yeast cells in the extract. One interesting thing is that Buchner hypothesized that yeast cells secrete proteins into their environment in order to ferment sugars, instead of the fermentation occurring inside the yeast cells, which is the actual mechanism.

Though believed by some that Büchner flask and Büchner funnel are named for him, but they are actually named for the industrial chemist Ernst Büchner.

Buchner received the Nobel Prize in Chemistry in 1907.

Personal life

Buchner married Lotte Stahl in 1900. During World War I, Buchner served as a Majorgay in a front-line field hospital at Focşanimarker, Romaniamarker. He was wounded on August 3 1917 and died of these wounds nine days later in Munich at age 57.
