In 1852 Adolf von Planta (1820 - 1895) had a laboratory in one aisle of Reichenau Castle built. On site 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 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 and was the first to propose a cyclic structure for benzene. The laboratory has been maintained in its original setting and is therefore a testimony of research from the mid-19th century.
