Uvod: Škola za sestre pomoćnice u Zagrebu od svog osnutka 1921. godine uz ravnatelja škole ima i sestru predstojnicu. U radu se pokušala učiniti rekonstrukcija školovanja i rada Jelke pl. Labaš Blaškovečka, prve nadstojnice u Školi za sestre pomoćnice u Zagrebu. Učinjen je i kratak osvrt na njezino djelovanje u družbi Kćeri Božje ljubavi kojoj se pridružuje nakon odlaska iz škole. Metode: Rekonstrukcija podataka temeljila se na fondovima Hrvatskog državnog arhiva (HDA) i Državnog arhiva u Karlovcu. Korišteni su podaci iz arhiva Provincije Božje providnosti Družbe Kćeri Božje ljubavi. Kao dopuna arhivskim izvorima korišteni su do sada objavljeni radovi na obrađenu temu. Rezultati: Uvidom u arhivsku građu i pregledom publikacija opisano je školovanje Jelke pl. Labaš Blaškovečka u Višoj djevojačkoj školi u Karlovcu, nastavak obrazovanja i djelovanje u Bolnici Crvenog križa Rudolfinerhaus u Beču. Opisani su uvjeti imenovanja za prvu nadstojnicu Škole za sestre pomoćnice u Zagrebu i njezin rad u vrijeme obavljanja te funkcije. Navedena su mjesta i pozicije na kojima je djelovala u Družbi Kćeri Božje ljubavi. Zaključak: Obrazovanje i iskustvo koje je Jelka pl. Labaš stekla radeći u Rudolfinerhausu u Beču primjenjivala je u izobrazbi sestara u Školi za sestre pomoćnice u Zagrebu. Svojim je radom doprinijela organizaciji škole u prvim godinama njenog djelovanja. Za šire razumijevanje njezina rada nakon odlaska iz škole u Družbu Kćeri Božje ljubavi bilo bi potrebno dodatno istražiti pismohranu Družbe. Introduction: School for nursing assistants in Zagreb since its founding in 1921, alongside the school principal, also had a nursing headmistress. The paper tried to reconstruct the schooling and work of Jelka Labaš Blaškovečka, the first headmistress at the School for Nursing assistants 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. Methods: The reconstruction of the data was based on funds from The Croatian State Archives and The National Archives in Karlovac. Data from the archive of the Province of God providence of the Daughters of Divine Charity was used. Published papers on the topic have been used as an addition to archival sources. Results: 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 headmistress of the School for Nursing assistants 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 Nursing assistants in Zagreb. With her work, she contributed to the organization of the school in the first years of its operation. For a broader understanding of her work in the Daughters of Divine Charity, further examination of its archives would be necessary.
