Dragiša after high school,  studied law, but because of his anti-communist and anti-regime belief, was expelled from the university. In Ljubljana subsequently managed to continue studying law. Meanwhile writes books for children and published his first two titles "Tales from the Zoo" and "Nasreddin." In 1952, the District Court in Dubrovnik sentenced Dragiša, as a student of the Law Faculty,  eight months in prison for attempting to illegally leave Yugoslavia. Kašiković managed to cross the border of Yugoslavia in 1955 and seize to Austria, where he stayed for two years. After a hard struggle for survival, with seven dollars in his pocket, he came to the United States. As written by the diaspora chronicles, he went over there to "fight against communism in the homeland and strengthens the Serbian spirit in exile with ancestral faith and human care." Upon arrival in Chicago he became editor of the emigrant newspaper "Freedom," a voice of  Serbian National Defense, which was about to close, but  Kašiković, quickly brings the reputation back, creating rich content and a active newspaper. In 1963 Kašiković runs a literary newspaper "Today" and the satirical newspaper "Velcro" and successfully runs radio program by Serbian National Defense. Translates  thousands of pages of text for Orthodox Church in America from English into Serbian, and all major institutions of the Serbian emigration rely on Dragiša's education, patriotism, enthusiasm and organizational skills. Dragiša Kašiković  graduated from college and perfectly mastered English, German and French in the US. Kašiković was 45 years old when he was killed in the night between 18th and 19th June 1977.

Ksenija Atanasijević was born on February 5, 1894 in Belgrade, the youngest of six children to Doctor Svetozar Atanasijević and Jelena Atanasijević, née Čumić, who died while giving her birth. Her father was a well-respected doctor and director of the State Hospital in Belgrade. Her mother's family was related to the famed Belgrade lawyer, writer and politician Aćim Čumić. Twelve years later, her father died. Ksenija's stepmother, Sofija Kondić, who taught at the Women's College (Viša ženska škola) in Belgrade, became her rightful guardian. Kondić was well-qualified to continue Ksenija's education. From Kondić Ksenija received her first lessons in philosophy: she learned quickly and eagerly, and no sooner another tragedy befall on her. Ksenija's older brother was killed in World War I. Ksenija's best friends while growing up were poet Rastko Petrović and his sister, painter Nadežda Petrović. While Ksenija attended the Lyceum, she was also influenced by Nada Stoiljković, her philosophy professor. Stoiljković suggested that Ksenija should take up philosophy with her former professor at Belgrade, Branislav Petronijević, and so, in the autumn of 1918, Ksenija Atanasijevic became Petronijevic's pupil at the University of Belgrade.

Authoritarian and demanding, Petronijević was exactly what Ksenija needed at that point. A brilliant professor and one of the most famous philosophers of his day in Serbia and elsewhere, he was a hard taskmaster. Petronijević's aim was to challenge his pupils to be able to maintain a philosophical discussion with their tutor. Ksenija was one of the most brilliant students ever to attend the university and it was not long before she attracted the attention of Belgrade's most distinguished intellectuals. She graduated in July 1920 with the highest marks in her graduating class, obtaining a university diploma in "pure and applied philosophy and classics." An excellent student, she decided to pursue an academic career in philosophy and soon after graduation, began working on a doctoral thesis on Giordano Bruno's De triplici minimo. She went to Geneva and Paris to seek out rare philosophical works and to discuss her thesis with specialists in the field, and on January 20, 1922, defended her Ph.D with honors in Belgrade before a panel of academics, including rector Jovan Cvijić, Mihailo Petrović, Milutin Milanković, Veselin Čajkanović, and Branislav Petronijević, her mentor. After her thesis was successfully defended, she became the first woman to hold a Ph.D. in Philosophy in Serbia. She was then 28 years old. In 1924, she became the first female university professor to be appointed to the Arts Faculty, Department of Philosophy at the University of Belgrade, where she taught classics, medieval and modern philosophy and aesthetics for twelve years. During her teaching career, she was a committed feminist both in theory and practice. She was a member of the Serbian Women's League for Peace and Freedom, the Women's Movement Alliance, and editor of the first feminist journal in the country, "The Women's Movement" (Ženski pokret), published from 1920 to 1938.

In 1936, she was removed from her university position on trumped-up charges of plagiarism because some of her male colleagues who worked alongside her felt threatened by her exceptional abilities. It was the result of a reaction to the liberal ideas she espoused and promoted and especially to her decision not to become part of an entirely male-dominated, academic ideological clique. Her sense of intellectual autonomy meant that not only was she unwilling to accept conservative ideologies structuring her teaching and writing, she was also capable of criticizing the work of her peers. At the time the Encyclopædia Britannica cited her study, The Metaphysical and Geometrical Doctrine of Bruno, written in French in Paris in 1924 as an authoritative work about an important and often neglected aspect of Bruno's philosophy. Her consequent dismissal caused a considerably outcry in Belgrade among intellectuals. At a public meeting where many people spoke in support of her, the most prominent speakers were law professor Živojin M. Perić and poets Rastko Petrović and Sima Pandurović.

He finished high school in Belgrade,  and graduated  History and Philology at the High School in Belgrade. In 1884 he went to Uzice and became a teacher in the local high school, where he taught French language, history and philosophical propaedeutics (Introduction to Philosophy). In 1902, he was transferred to Belgrade. That same year he laid professorial exam with the theme "The Impact of Eastern civilization to European nations".His translations from English history of civilization in England H. T. Berke Belgrade (1893-1894) and about heroes Thomas Carlyle (Belgrade, 1903) are highly important.
He died in 1905 as a professor of the First Belgrade Gymnasium.

Branko Pešić (1922–1986) was a member of the Yugoslav resistance forces during the World War II in Yugoslavia, and later leader of the Yugoslav Communist party in Belgrade and Mayor of Belgrade from 1964 to 1974.

Pešić was one of the most famous Belgrade mayors, and his decade-long saw the construction of many important projects including the Mostar interchange, Gazela Bridge, and Terazije Tunnel.

As a scientist, he was the first to distinguish between the genus Archaeopteryx and the genus Archaeornis; he also discovered new characteristics of the genera Tritylodon and Moeritherium. Petronijević's great scientific fame, however, is nearly eclipsed by his still greater philosophical renown, which he owes to his three principal philosophical works, Principi Metafizike (Principles of Metaphysics), O Vrednosti života (About Value of Life), Istorija novije filozofije (History of a Newer Philosophy).Branislav Petronijević, world-renowned Serbian philosopher and paleontologist, was born in a small village of Sovljak, near Ub, Serbia, on the 25th of March 1875, the son of a priest, originally from Montenegro. He had as a youth a taste for collecting objects of natural history and other curiosities while a student at a gymnasium (high school) in Valjevo and the Grande école in Belgrade. This led him to the study of medicine, which he went to Vienna to pursue, eventually after the third semester directing his attention to psychiatry, philosophy, biology and paleontology. Petronijević joined the Philosophical Society of the University of Vienna and studied under Ludwig Boltzmann. After years in Vienna he travelled to Germany with a view to further philosophical study. There he studied at the University of Leipzig under Johannes Volkelt, Wilhelm Ostwald, and Ernst Mach. With his metaphysical writings,"Der ontologische Beweis fűr das Dasein des Absoluten," he proved himself a worthy student of Professor Wilhelm Wundt, "the father of experimental psychology," successfully defending his thesis in 1898. From Leipzig he went back to Belgrad, where he wrote and published "Der Satz vom Grunde" in 1898. It was during this period, however, that he thought out and developed what is distinctive in his philosophical doctrine. His eclecticism, his ontology and his philosophy of history were declared in principle and in most of their salient details in the "Prinzipen der Metaphysik" (2 volumes, Heidelberg, 1904–1911) and "Die typischen Geometrien und das Unendliche" (Heidelberg, 1907). In 1898 he was given the post of privatdozent in the Grande école of Belgrade and seven years later when his alma mater became the University of Belgrade he was appointed associate professor. At the outbreak of World War I he turned to journalism, becoming a war correspondent for the Serbian War Office Press Bureau, induced by Col. Dragutin Dimitrijević, his childhood friend. In 1915 he joined the Serbian army's retreat through Albania (World War I). After reaching Greece, he was sent to London with the Serbian Legation, along with politician Nikola Pašić, geographer Jovan Cvijić, professors Bogdan Popović and his brother Pavle Popović. A man who impressed me, not so much by his ability as by his resolute absorption in philosophy even under the most arduous circumstances, was the only Yugoslav philosopher of our time, whose name was Branislav Petroniević. I met him only once, in the year 1917. The only language we both knew was German and so we had to use it, although it caused people in the streets to look at us with suspicion. The Serbs had recently carried out their heroic retreat before the German invaders, and I was anxious to get a first-hand account of this retreat from him, but he only wanted to expound his doctrine that the number of points in space is finite and can be estimated by considerations derived from the theory of numbers. The consequence of this difference in our interests was a somewhat curious conversation. I said, "Were you in the great retreat?" and he replied, "Yes, but you see the way to calculate the number of points in space is." I said, "Were you on foot?" and he said, "Yes, you see the number must be a prime." I said, "Did you not try to get a horse?" and he said, "I started on a horse, but I fell off, and it should not be difficult to find out what prime." In spite of all my efforts, I could get nothing further from him about anything so trivial as the Great War. I admired his capacity for intellectual detachment from the accidents of his corporeal existence, in which I felt that few ancient Stoics could have rivalled him. After the First War he was employed by the Yugoslav Government to bring out a magnificent edition of the eighteenth-century Yugoslav philosopher Boscovic, but what happened to him after that I do not know.

After the war he left London and went back to his teaching post at the University of Belgrade, where he was appointed extraordinary professor (1919). In 1920, he was elected into the Serbian Royal Academy and at the same time he attracted the notice of other foreign philosophers with whom he had a lively correspondence in both philosophy and science. He wrote numerous papers on philosophy and science in English, French, German, Polish and Serbian learned journals.

We see in "L'Évolution universelle" very distinctly the fusion of the different philosophical influences by which his opinions were finally matured. For Petronijević was an eclectic in thought and habit of mind as he was in philosophical principle and system. It is with the publication of the L'Évolution of 1921 in Paris that the first great widening of his reputation is associated.

Also, he undertook the task to translate Ruđer Bošković's "A Theory of Natural Philosophy" mentioned by Russell. As far as we know, this is the first time that the work was translated from Latin to a modern language (English). It is prefaced by the "Life of Roger Joseph Boscovich," written in English by Branislav Petronijević, and an explanatory introduction by the translator. Bošković's "A Theory of Natural Philosophy" is a work of considerable importance in the history of physical theory and his atomic hypothesis were of particular interest when it was first published in London by Open Court Publishing Company in 1922. Petronijević retired from the university in 1927. Ksenija Atanasijević was one of his disciples. He stopped working altogether from the time the Axis invaded the Kingdom of Yugoslavia (1941) until his death. He was staunch anti-fascist and anti-communist and could not accept the fact that Yugoslavia was dragooned behind the Iron Curtain. Perhaps for this reason he was left ignored and forgotten, like most of his post-World War I colleagues who were in sympathy with the Old Order. His old age was spent in obscure poverty, his friends and associates having fled to the West, killed in the war, or passed away before him. Petronijević died in a Belgrade hotel on the 4th of March 1954. He was 79. He never married.

He was born in Smriječno village near Plužine, then in the Kingdom of Serbs, Croats and Slovenes. He was a Belgrade Law School graduate and a professor of philosophy at the University of Belgrade Faculty of Philosophy as well as a member of the Serbian Academy of Sciences and Arts. His father Pavle Tadić was a lieutenant of the Montenegrin Army in the wars against the Ottomans. Pavle opened the first school in Piva, during the Kingdom of Yugoslavia.

Tadić was one of the founders of the Democratic Party (DS) in Serbia in December 1989. He was one of the leaders of the pro-European movement in Serbia. Tadić was of the Piva Herzegovinian clan.

Tadić was married to psychiatrist Nevenka Tadić and had two children. His son Boris Tadić served as the President of Serbia from 2004 to 2012. Ljuba Tadić died in Belgrade, Serbia, aged 88.

Ljubomir Nedić was born in Belgrade, Serbia, on the 24th of April 1858. His philosophical work was neglected by the historians of Serbian philosophy from the moment the Nazi occupied the country in 1941 and suppressed after the end of World War II by the communists who took power. It wasn't until the break-up of Communist Yugoslavia in 1990s did an interest in his work re-kindle. Nedić was educated chiefly in Belgrade, Jena and Leipzig where he studied medicine, attending lectures on anatomy and psychology and visiting hospitals. After some contemplation he abandoned medecine in favour of philosophy, logic and psychology. Ljubomir Nedić was a student of the world renowned Wilhelm Wundt, "the father of experimental psychology". Nedić's doctoral thesis, defended in 1884, was on contemporary British logic, primarily that of Sir William Hamilton. In 1885 he was made a doctor of philosophy at the University of Leipzig in recognition of Die Lehre von der Quantification des Pradikats in der neuern englische Logik (The Doctrine Concerning the Quantifie d Predicate in Recent English Philosophy) his year-long research paper written in London. After ten years spent abroad studying at Jena, Leipzig and London universities, he completed his doctorate under Wundt, and obtained a professorship at Belgrade's Grande École (Velika Škola), where he acquired great influence by the dignity of his personal character. In Belgrade in 1889 he wrote and published O sofizmima (On Sophisms)., which brought him more recognition. During the following years he published works on Plato and Socrates, as well as a history of philosophy. The strain of the 14 years of continuous work undermined his health and he was compelled to retire from his professorship at the Grande École (which became accredited as the University of Belgrade in 1905) in 1899. After his retirement he further developed his philosophical position, a speculative eclecticism through which he endeavoured to reconcile metaphysical idealism with the naturalistic and mechanical standpoint of science. In 1890, two groups were formed in literary criticism: one led by Nedić, and the other by the critics gathered around the literary journal Delo. Nedić was the first to apply in the 1890s aesthetic criteria to literature in his theoretical and critical contributions to the periodical Srpski pregled, of which he was the editor.

In 1901 Nedić published his second book "Noviji srpski pisci", as an introduction included the chapter "O književnoi kritiki". By then, he was already established as a Serbian new literary critic.
Thought

Ljubomir Nedić's significance in the history of Serbian thought depends on his position as the philosopher of the great scientific movement of the second half of the nineteenth century, and of the friendship and admiration with which he was regarded by Wundt, and all of his contemporaries, disciples of Hamilton, and Spencer.

His part in philosophy and logic was that of a historian and commentator, for which he was especially qualified by his clarity of exposition; his point of view is one of the main Hegelian traits. His Die Lehre von der Quintification des Pradikats in der neueren englische Logik (Leipzig, 1885) is perhaps the most accredited modern work of its kind before the start of the 20th century. He made valuable contributions to the study of modern literary criticism, along with Svetozar Marković, Jovan Skerlić, Bogdan Popović, Pavle Popović, Slobodan Jovanović, and Branko Lazarević. His work was quoted in Johann Eduard Erdmann's Logic and Methaphysics (1892) and Wilhelm Wundt's Textbook of Logic (1893) even before the start of the 20th century. He died at Belgrade on the 29th of July 1902.
His Work

The last years of his life were devoted chiefly as a literary critic. He aimed sharp criticism at the utiliterian theory of art espoused by the late Svetozar Marković, who accentuated the social role of literature in Realism. Quite the opposite, Nedić empasized the aesthetic side of the lyric poem, using Vojislav Ilić's work as examples. In 1893 he founded and edited Srpski pregled, a literary review, for which he also acted as a literary and dramatic critic, and the influence of his individuality soon made itself noticed. His books in literary criticism are still being reprinted, Iz novije srpske lirike (1893), Noviji srpski pisci (1901), and Kritičke studije (1910).

As an academic critic educated abroad, Ljubomir Nedić and Bogdan Popović are responsible for the development of Serbian Modernism in prose, verse and art.
