The ancestors of Antun Fabris came to the mainland from the island of Korčula. After finishing basic studies in Dubrovnik he went on to Vienna, where he graduated in Slavic studies from the university there in 1889. He was a teacher first in Split and then Zadar. In 1895 he became the Editor of the prominent Dubrovnik newspaper. In 1902 he formed his own paper in Dubrovnik, the Srđ, with his wife, and professor Luko Zore, the editor-in-chief, and the support of other Catholic Serbs, including Lujo Bakotić, the author of "Serb People in Dalmatia from the Fall of Venice to the Unification." It was a science and culture journal for Serb intellectuals in Dalmatia, published twice a month until 1908 in both Cyrillic and Latin scripts, with cooperation of many intellectuals across Dalmatia and several writers from Mostar, notably Aleksa Šantić, Jovan Dučić, Marko Car and Vladimir Ćorović, as well as some from Serbia, namely Jovan Jovanović Zmaj. The Srđ contributed greatly to the preservation of Dubrovnik's rich cultural and historical heritage. As a respected Serb journalist, he was a Deputy President of the Pan-Serb Journalist Congress in Belgrade on 14 and 15 October 1902. In 1940 a book entitled Izabrani članci Antuna Fabrisa was published by H. Barić. For publishing in the Srđ the song of Uroš Trojanović "Boccan night" dedicated to the youth of Boka kotorska Antun was under ideological accusations arrested on 5 November 1902 and kept in prison until 23 December 1902. Three others were also arrested, interrogated and imprisoned, Uroš Trojanović, the author of the poem, Luko Zore, and Antun Pasarić, Fabris's co-editors. Fabris's term, however short in prison, greatly jeopardized his poor health, causing his premature death in 1904. The Srđ was taken over by Antonije Vučetić. Co-editors of the Srđ were Kristo Dominković, Luko Zore, Miho Vacchetti, Antun Pugliese, Uroš Desnica, and others. Contributing writers included Pero Budmani, Medo Pucić, Niko Pucić, Valtazar Bogišić, Matija Ban, Ivan Stojanović, Milan Rešetar, Vicko Adamović, Lujo Adamović, Lujo Vojnović, Marko Murat, Pero Kolendić, Frano Kulišić, Ignjo Job, Stijepo Kobasica and others. Fabris was also the owner, editor, and co-editor of the periodical "Dubrovnik", between 1897 and 1914 as well as the manager of Dubrovnik's "Matica srpska". Fabris was a great admirer of Nikola Pašić. He greatly contributed to the initiative to found the "Srpska Zora"-"Српска зора", a Dalmatian Serb cultural society in 1901.
