Mariano San Nicolò a Otakar Sommer pohledem (nejen) jejich korespondence

The text is based on the correspondence preserved in the estates of prof. Otakar Sommer and prof. Miroslav Boháček stored in the Archives of the Czech Academy of Sciences (Prague). Based on these letters, it turns out that the traditional views on non-communication between professors at Charles University and the German University in Prague are not entirely true. There were professional and collegial contacts between the Czech and German Romanists, which in the case of O. Sommer and prof. Mariano San Nicolò also turned out to friendship, even between their families. Letters written by M. San Nicolò also partially show the background of his departure from Prague and his pedagogical work in Munich. The aim of the article is to point out the fact that correspondence between the academics of that time is an important source of knowledge about the scientific community of interwar Czechoslovakia.
