In 1852 Adolf von Planta (1820-1895) had a laboratory built in a wing of Reichenau Castle. There, von Planta performed research in natural sciences such as water and soil analysis, physiological processes, and botany. Between 1852 and 1853, he was assisted by August Kekulé (1829-1896), who had just completed his doctoral studies under the supervision of Justus von Liebig. They worked together on alkaloid analysis e.g. nicotine. Later in his career, Kekulé made important discoveries in organic and structural chemistry, which include the tetravalency of the carbon atom or the proposition of a cyclic structure for benzene. The laboratory has been conserved in its original setting and is therefore a testimony to research of the mid-19th century.

The award ceremony was held on 12 September 2014 in Reichenau, during which a commemorative plaque was unveiled and affixed at the entrance of the castle.

The ceremony was opened by Prof. Dr. Katharina Fromm, President of the «Platform Chemistry» of SCNAT, who welcomed the audience and presented the «Chemical Landmark» program. Gian-Battista von Tscharner, today's owner of the Reichenau castle, then presented a retrospective of the site. The importance of Kekulé's contributions to chemistry was emphasised in the laudation of Prof. Dr. Richard R. Schrock, professor at MIT and Nobel laureate in chemistry 2005.
