The Institutes of Pharmacology and Food Chemistry of the Goethe-Universität in Frankfurt am Main by Ferdinand Kramer soon advanced to a highly appreciated master work of modern post-war architecture. After a comprehensive renovation by the architects SSP Schürmann-Spannel in the years 2009 to 2013, the concrete structure with its striking brises soleil on the south side and the lecture-hall cube detached from the main building, is not only again a convincing built monument, but also an exemplary example of a successful conversion. Where for many years students of pharmacology and food chemistry studied and experimented, 160 scientists of the Biodiversity and Climate Research Centre (BiK-F) are researching the interaction of climate and biosphere.
