From Windhoek to Kamina to Nauen listens to the present-day echoes of telegraphy between Nauen (Germany), Kamina (Togo), and Windhoek (Namibia). Wireless telegraphy (a precursor of today’s global internet technology) is an integral part of the history of colonial violence, wars, and genocides. Radio telegraphy was used for the first time worldwide as a mobile means of military communication during the war against the Herero and the Nama 1904–1908 which ended in genocide. Subsequently, from 1910 onwards a permanent radio connection between the German Reich and its colonies was built. These installations were used from 1914 on, but were destroyed when Namibia was occupied by the South Africa at the beginning of World War I. This workbook is the beginning of a conversation about the colonial use of telecommunications and its effects between scientists and artists from Namibia, Togo and Germany
