Two eighteenth century cartographic sources used for the construction of a historical GIS database dedicated to Transylvania

Beyond these inadequacies, it represents an important source, which mentions the motto of the institution, the first visitors on 25 June 1899, headed by the mayor of the city, Friedrich Walbaum and a number of other local personalities of that time. We have signatures of anonymous and famous visitors who crossed the threshold of the institution between 1899 and 1918. Among these signatures we find those of Professor Friedrich Brewerth, the future scientist Hermann Oberth, the collector Karl Haldenwang or the scientist Alexander Tzigara-Samurcaș. The presence of signatures from 1914–1918 also shows that the institution functioned during the difficult years of the First World War.
