In 1911, after finishing the basic school with distinction, he started to study Law at his father's request, although his passion was zoology. After passing the first state exam, he moved on October 1, 1913 to Nevesinje, Herzegovina, in order to serve as a one-year volunteer in the Austria-Hungary's mountain artillery. When the war broke out, he came to the Serbian front. He was wounded in 1914 and in 1918 was decorated first lieutenant and battery commander while in captivity in Trento, Italy, returning home in October 1919. After finishing his law studies, he began to study natural history in 1920, especially the biological subjects, and earned his doctorate on February 10, 1923 with the thesis "Monographie der Prorhynchidae (Turbellaria Alloeocoela)". The turbellarians remained his subject of interest throughout his life.
