He was born in 1898 in Prijedor in Bosnia-Herzegovina, in the house of Orthodox priests. He inherited such a patriarchal family's firmness and stability, from people who grew up in that very soil and he spent his whole life being so ingrained, not giving up on the deepest and unchanged moral principles. He belonged to the Young Bosnia Movement where he was, as a juvenile pupil of the Tuzla's high school, sentenced to 10 years in prison. He was also shortly engaged adventurously in national interests at the end of the First World War.

Stojanović became a sculptor after going to study, first in Vienna at the beginning of 1918, and later in Paris. He received his scholarships from Dr. Djurica Djordjević and his wife Krista, who he became acquainted and afterward became friends with. They were big defenders of the modern art in between-the-wars Yugoslavia and their house became one of the most known meeting places of artists, writers, young left-wing politicians and intellectuals.Being in the midst of social happenings, he returned to Bosnia immediately after the end of the war where he was engaged in creation of first Yugoslavia, with all his achieved political and penal reputation, belligerence and revolutionary mood.

In 1919, Stojanović went to Paris to pursue the best studies of art, which not only ensured the necessary education but also close contacts with numerous life's challenges and a creative stimulation coming from one of the biggest European metropolises.

During the Second World War he lived in Belgrade with his family. After the war, Stojanović engaged himself in many functions. He was the chairman of the National Front in Belgrade, commoner, the secretary of the Association of Painters of Yugoslavia, the chairman of the Association of Painters of Serbia, the principal of the Art Academy, the editor of the magazine "Art", a member of Serbian Academy of Art and Sciences in 1950, etc.

He died in Belgrade in 1960, leaving behind one of the most valuable sculpture opuses in the Serbian art of the 20th century. For his birthplace Prijedor he gave a gift of an important part of his artworks. His creations can also be seen in the gallery Pavlo Beljanski in Novi Sad, the National museum and the Museum of modern art in Belgrade. In memorial buildings in Belgrade, Vojvodina, Montenegro and Republic of Srpska in Bosnia-Herzegovina there are some of his most important monumental compositions.
