Sigismund Friedrich Hermbstädt

Sigismund Friedrich Hermbstädt (* 16. April 1760 in Erfurt; † 22. October 1833 in Berlin) was a pharmacist, chemist, technical writer, technologist and “management consultant”.

Hermbstädt used itself time of its life for the spreading relating to crafts and industrieller techniques. For this it heldInstruction courses for manufacturing ones off and a multiplicity of papers and books published in which it with the technologies as well as the physics and chemistry of the represented procedures dealt. It made a substantial contribution for the modernization and rationalization of agriculture, industry and trade in Prussia beginning of theearly 19. Century.

lives

after which it in its hometown the pc. Hermbstädt at the university had visited, began Michaelisschule, one elementary school, and 1773 to 1774 the advice High School to Erfurt a study of the medicine science. Additionally it visited lectures on chemistry with Trommsdorf. To the graduation it went as Repetent to Langensalza into from Johann the Christian weigh-lives justified pharmaceutical institute. Danach nahm er ein Officium in to give to Ratsapotheke in Hamburg an. 1784 he worked as a manager in the pharmacy to the white swan, the pharmacy of thethe deceased Valentin rose the older one in until 1780 also the Martin Heinrich Klaproth was active. It at the same time continued its studies at the royal Collegium medico chirurgicum, there learned it also professor Dr. Place, body physician of the Prussian king and secret advice, know. 1786 it undertook a study tripinto the resin and into the Saxonian ore mountains. In Goettingen , Leipzig and free mountain resound stayed it longer and closed acquaintance with personalities such as Johann Beckmann, George Christoph Lichtenberg, Johann Friedrich Gmelin, Johann George Adam Forster, Ernst Hebenstreit, Abraham God praise Werner, Christlieb honour God Gellert, Johann Friedrich Lempe and Johann Gottfried Hoffmann. At the end of of 1787 denationalized Hermbstädt again in Berlin and held private lectures on chemistry, physics, technology and pharmacy. 1791 took place its appointment as a tidy professor for chemistry and pharmacy to that Collegium medico chirurgicum. At the same time one entrusted it also with the administration of the royal yard pharmacy, a task which it 7 years long noticed. In this time the appointment as the advice at the Obercollegium medicum, as the Assessor the royal of the Manufactur and Commerzcollegiums took place as well as to the Assessorthe salt administration. Latter caused its co-operation in chemical-technological questions in the department of the Minister Karl August von Struensee. Because of a rebellion on the sugar island San Domingo (Haiti) became sugar 1791 in Prussia scarcely and expensively. Hermbstädt should look therefore for substitute solutions. Although AndreasSigismund Marggrafs and Franz Karl Achards work admits was accomplished Hermbstädt own investigations at native plants like Turkish wheat, Bärenklau, Birken, carrots and other plants. In the long run its work, like its “adversary” oh pool of broadcasting corporations, remained in outgoing 18. Century without success.
Other ranges became throughit more affects. With nearly all applications of the technology at that time, the agriculture and pharmacy busy Hermbstädt and published itself over it papers and provided in such a way for a spreading existing practice knowledge (Best practice). It was concerned with as different things as mechanism of a Zuckersiederei, Durckverfahren,Production of white lead, Färberei, tannery, Branntweinherstellung, beer brewing, refinement of flax and hemp, cultivation of the tobacco plant and many other technologies.
1810 were appointed Hermbsstädt to suggestion of Alexander of Humboldt and Johann Gottfried Hoffmann as an extraordinary professor for technology to the again created university. Starting from 1816Hermbsstädt held also lectures at the mountain academy in free mountain (Saxonia).

Hermbstädt had substantial influence also on chemical thinking of its time. Its translation of the works Lavoisiers, whose Traité published élémentaire chimie it as Mr. Lavoisiers system of anti-inflammatory chemistry 1792, ledto a rapid break with the Phlogiston - theory. Also around the rapid spreading of the new of chemical nomenclature (Lavoisier, Berthollet, Guyton de Morveau (1787) Hermbstädt made itself earned.
