[History of the Pathologic Museum of the Berlin Charité. 3. On the microcephalic brothers Michael and Friedrich Sohn of Kiwitsblott].

The historical events relating to 2 microencephalic brothers born in Prussia around 1815 and 1822 are presented. After their deaths in 1835 and 1842 respectively they were made accessible to the anatomical museum of the Berlin University. Later the skulls, casts and detailed contemporary descriptions of their development and behaviour as well as original correspondence relating to obtaining the specimens came to the Pathologic Museum of the Charité where they can be found today (recently rediscovered).
