The civil engineer and geodesist Vincenc Vinko Hlavinka (1862-1934) worked in Zagreb for 23 years after studying in Vienna. His pedagogical activities and projects are described, along with his significance for the development of geodesy and technology in Croatia and his activities after he returned to Czechoslovakia, where he was a professor at the Higher Technical School in Brno, among other things. Hlavinka was actively engaged after his return in the development of Czechoslovak-Croat relationships, and his efforts for the Czechoslovak-South Slavic League were particularly noted. As its president, he organised trips to Yugoslavia for individuals and groups, initiated the establishment of the South Slavic College in Brno, and helped the Croatian minority in southern Moravia.; Građevinski inženjer i geodet Vincenc Vinko Hlavinka (1862–1934) nakon studija u Beču 23 je godine znanstveno djelovao u Zagrebu.
