As leader of the "Eismitte" (Mid-Ice) campsite Dr. Johannes Georgi (1888-1972) lived from July 31, 1930 to August 7, 1931 in a firn cave at the site and conducted important scientific experiments at temperatures as low as minus 60°C. Station Mid-Ice was located between the east and the west coast of Greenland, with a distance of about 400 km to each coast. Upon his return Georgi was appointed director of the department for equipment and instruments at the naval observatory in Hamburg. In November 1871 – only a few months before his death – he visited the watch and clock museum in Wuppertal and donated his expedition chronometer to Jürgen Abeler’s collection.
