The bulk of the correspondence in the Geologenarchiv comes in two major gro
ups:a) letters relating mainly to professional matters and b) letters conta
ining predominantly personal communication. This will be demonstrated by ma
terial relating to the three above mentioned Viennese Geologists: Leopold K
ober's letter to Wilhelm Salomon-Calvi and the correspondence between Alois
Kieslinger and Eugen Wegmann are mainly professional, whereas Otto Ampfere
r's letters to the Bavarian glaciologist Edith Ebers are a documentation of
personal friendship.
