Slobodan Pejić (19 June 1944 – 25 August 2006) was a Bosnian sculptor and painter who lived for most of his life in Slovenia. He is best known after having transformed a 300-year-old oak tree that fell in the storm in Tivoli Park in Ljubljana into the sculpture Coexistence in 2000, proposing with the act the beginning of a sculpture garden (forma viva) in the park. He painted numerous frescos in Bosnia and Croatia. In addition, he invented a new technique in sculpture, based on moulding and gas expansion. He was for many years the Ljubljana correspondent of the Tanjug press agency.
Pejić was born during a bomb raid of German forces in World War II, on a field, in Balatun, located north of Bijeljina in what is now Republika Srpska. His father was a well-known architect, and his mother was a daughter of Bosnian worthies. As a boy, Pejić was educated by the Austrian painter Karl Matzek, with whom he studied for almost ten years, and who was the only father Pejić really knew. Matzek also married his mother, but then moved to Australia in 1958 and the family retained only written contacts, including art books and art magazines regularly sent by Matzek to Pejić. Apart from Matzek, the young boy was most influenced by the Drina River, where he was spending his youth. He was also marked by the works of the Bosnian poet Mak Dizdar, and some of Dizdar's verses became his life motto. In his home village, Pejić was ascribed magical powers, and helped people as a healer.
Immediately after having graduated from high school, Pejić moved to his own. He studied in Belgrade and earned his living as a clarinetist in a jazz band and as a scenographer in the National Theatre. There, he moved in the company of the best known Yugoslav theatre directors, actors and journalists, participating in their lively discussions, especially in the old Triglav Café. Later, he moved to Germany, and then to Ljubljana, where he studied journalism. He remained there for the rest of his life. Pejić worked for years as a special Ljubljana correspondent to the Tanjug press agency.
