School for nurses in Zagreb since its founding in 1921, alongside the school principal, also had a nursing superintendent. The paper tried to reconstruct the schooling and work of Jelka Labaš Blaškovečka, the first superintendent at the School for Nurses in Zagreb. A brief review shows her work in the Daughters of Divine Charity (international congregation of Roman Catholic religious sisters), which she joined upon finishing school. The insight into the archives and examination of publications was used to describe the schooling of Jelka pl. Labaš Blaškovečki at the Girls’ High School in Karlovac, as well as a continuation of her education and work in Red Cross Hospital at the Rudolfinerhaus in Vienna. Terms of appointment for the first superintendent of the School for Nurses in Zagreb and her work then is described. Her workplaces and job positions in the Daughters of Divine Charity are listed. Conclusion: Jelka pl. Labaš applied her education and experience that she acquired while working at the Rudolfinerhaus in Vienna in training nurses at the School for Nurses in Zagreb. With her work, she contributed to the organization of the school in the first years of its operation.
