2003	Justus von Liebig in Giessen	On May 16, 2003, on the occasion of Justus Liebig's 200th birthday, his former laboratory was named a Historic Site of Chemistry. Today's Liebig Museum in Gießen was originally a guard house of a barracks and was gradually rebuilt by and for Liebig during his time as a professor at what was then Ludwig University from 1824–1852. While the professor was still doing research in a dark room by an open fireplace in the “old laboratory”, at the end of Liebig's time there were closed fume cupboards and a comparatively modern lecture hall in which experiments for the training of students could be demonstrated. At Robert Sommer's endeavor , the building, which had largely remained in its original state, was acquired in 1912 and opened as a museum in 1920. The appreciation brochure of the GDCh particularly emphasizes how popular and respected Liebig was with his students because he supervised them personally and applied a new teaching method by explaining and justifying experiments carried out during the lecture. Liebig is therefore also considered a study reformer. In addition to many Germans, 221 from 11 other countries studied with him. Have become famous August Wilhelm von Hofmann , Friedrich August Kekule , Max von Pettenkofer , Wilhelm Henneberg , Carl Schmidt , Lyon Playfair , Ascanio Sobrero and Eben Norton Horsford .

2011	Robert Wilhelm Bunsen in Heidelberg	On October 12, 2011, the former chemistry laboratory in Akademiestraße / Plöck 55 was recognized as the place of work by Robert Wilhelm Bunsen . The occasion was the 200th birthday of the chemist, who is considered one of the pioneers of physical chemistry. Together with Gustav Kirchhoff, he developed spectroscopy , which enabled the discovery of the elements cesium and rubidium . The building, built in 1854/55, was equipped with heating, running water, gas and electricity and was considered the most modern chemical laboratory in Europe at the time. In the period from 1852 to 1889 Robert Bunsen was director of the chemical laboratory at Heidelberg University. The building, which was used as part of the Chemical Institute until the end of the 1950s, now houses the Institute for German as a Foreign Language Philology.

2012	Former salicylic acid factory and later chemical factory Dr. F. von Heyden, Radebeul	The former salicylic acid factory and later chemical factory Dr. F. von Heyden, Radebeul , is the former place of work of Jacob Friedrich von Heyden , Adolf Wilhelm Hermann Kolbe , Rudolf Wilhelm Schmitt , Bruno Richard Seifert , Richard Gustav Müller . Kolbe recognized the fungicidal and antibacterial effects of salicylic acid, for which he found two synthetic routes; the first by passing carbon dioxide over phenol ; the second method was suitable for industrial production: conversion of heated sodium phenolate with carbon dioxide. Von Heyden manufactured it using this process from 1874. Schmitt and his student Seifert explained the mechanism of the reaction, which led to the fact that the carbon dioxide was then applied under pressure to increase the yield. Richard Seifert also developed the recipe for Odol , which was then manufactured and successfully marketed by August Lingner . Richard Müller is known as the "German father of silicone chemistry ". He joined the von Heyden company in 1934 and received the first silicone from his so-called direct synthesis in 1940: when CH ₃ Cl is passed over a copper-silicon alloy when heated, mainly dimethyldichlorosilane is formed , the hydrolysis products of which result in polysiloxane plastics (silicones) when condensed .
