Mircea Eliade (Romanian: ['mirtSea eli'ade]; March 9 [O.S. February 24] 1907 - April 22, 1986) was a Romanian historian of religion, fiction writer, philosopher, and professor at the University of Chicago. He was a leading interpreter of religious experience, who established paradigms in religious studies that persist to this day. His theory that hierophanies form the basis of religion, splitting the human experience of reality into sacred and profane space and time, has proved influential.

Born in Bucharest, he was the son of Romanian Land Forces officer Gheorghe Eliade (whose original surname was Ieremia) and Jeana nee Vasilescu. An Orthodox believer, Gheorghe Eliade registered his son's birth four days before the actual date, to coincide with the liturgical calendar feast of the Forty Martyrs of Sebaste. Mircea Eliade had a sister, Corina, the mother of semiologist Sorin Alexandrescu. His family moved between Tecuci and Bucharest, ultimately settling in the capital in 1914, and purchasing a house on Melodiei Street, near Piata Rosetti, where Mircea Eliade resided until late in his teens.  Eliade kept a particularly fond memory of his childhood and, later in life, wrote about the impact various unusual episodes and encounters had on his mind. In one instance during the World War I Romanian Campaign, when Eliade was about ten years of age, he witnessed the bombing of Bucharest by German zeppelins and the patriotic fervor in the occupied capital at news that Romania was able to stop the Central Powers' advance into Moldavia.  He described this stage in his life as marked by an unrepeatable epiphany. Recalling his entrance into a drawing room that an "eerie iridescent light" had turned into "a fairy-tale palace", he wrote,  I practiced for many years [the] exercise of recapturing that epiphanic moment, and I would always find again the same plenitude. I would slip into it as into a fragment of time devoid of duration--without beginning, middle, or end. During my last years of lycee, when I struggled with profound attacks of melancholy, I still succeeded at times in returning to the golden green light of that afternoon. [...] But even though the beatitude was the same, it was now impossible to bear because it aggravated my sadness too much. By this time I knew the world to which the drawing room belonged [...] was a world forever lost.  Robert Ellwood, a professor of religion who did his graduate studies under Mircea Eliade, saw this type of nostalgia as one of the most characteristic themes in Eliade's life and academic writings.  After completing his primary education at the school on Mantuleasa Street, Eliade attended the Spiru Haret National College in the same class as Arsavir Acterian, Haig Acterian, and Petre Viforeanu (and several years the senior of Nicolae Steinhardt, who eventually became a close friend of Eliade's). Among his other colleagues was future philosopher Constantin Noica and Noica's friend, future art historian Barbu Brezianu.  As a child, Eliade was fascinated with the natural world, which formed the setting of his very first literary attempts, as well as with Romanian folklore and the Christian faith as expressed by peasants. Growing up, he aimed to find and record what he believed was the common source of all religious traditions. The young Eliade's interest in physical exercise and adventure led him to pursue mountaineering and sailing, and he also joined the Romanian Boy Scouts.  With a group of friends, he designed and sailed a boat on the Danube, from Tulcea to the Black Sea. In parallel, Eliade grew estranged from the educational environment, becoming disenchanted with the discipline required and obsessed with the idea that he was uglier and less virile than his colleagues. In order to cultivate his willpower, he would force himself to swallow insects and only slept four to five hours a night. At one point, Eliade was failing four subjects, among which was the study of the Romanian language.  Instead, he became interested in natural science and chemistry, as well as the occult, and wrote short pieces on entomological subjects. Despite his father's concern that he was in danger of losing his already weak eyesight, Eliade read passionately. One of his favorite authors was Honore de Balzac, whose work he studied carefully. Eliade also became acquainted with the modernist short stories of Giovanni Papini and social anthropology studies by James George Frazer.  His interest in the two writers led him to learn Italian and English in private, and he also began studying Persian and Hebrew. At the time, Eliade became acquainted with Saadi's poems and the ancient Mesopotamian Epic of Gilgamesh. He was also interested in philosophy--studying, among others, Socrates, Vasile Conta, and the Stoics Marcus Aurelius and Epictetus, and read works of history--the two Romanian historians who influenced him from early on were Bogdan Petriceicu Hasdeu and Nicolae Iorga. His first published work was the 1921 Inamicul viermelui de matase ("The Silkworm's Enemy"), followed by Cum am gasit piatra filosofala ("How I Found the Philosophers' Stone"). Four years later, Eliade completed work on his debut volume, the autobiographical "Diary of a Short-Sighted Adolescent" translated into English and published by Istros Books in 2016.  At signs that the Romanian communist regime was about to take hold, Eliade opted not to return to the country. On September 16, 1945, he moved to France with his adopted daughter Giza. Once there, he resumed contacts with Dumezil, who helped him recover his position in academia. On Dumezil's recommendation, he taught at the Ecole Pratique des Hautes Etudes in Paris. It was estimated that, at the time, it was not uncommon for him to work 15 hours a day. Eliade married a second time, to the Romanian exile Christinel Cotescu. His second wife, the descendant of boyars, was the sister-in-law of the conductor Ionel Perlea.  Together with Emil Cioran and other Romanian expatriates, Eliade rallied with the former diplomat Alexandru Busuioceanu, helping him publicize anti-communist opinion to the Western European public. He was also briefly involved in publishing a Romanian-language magazine, titled Luceafarul ("The Morning Star"), and was again in contact with Mihail Sora, who had been granted a scholarship to study in France, and with Sora's wife Mariana. In 1947, he was facing material constraints, and Ananda Coomaraswamy found him a job as a French-language teacher in the United States, at a school in Arizona; the arrangement ended upon Coomaraswamy's death in September.  Beginning in 1948, he wrote for the journal Critique, edited by French philosopher Georges Bataille. The following year, he went on a visit to Italy, where he wrote the first 300 pages of his novel Noaptea de Sanziene (he visited the country a third time in 1952). He collaborated with Carl Jung and the Eranos circle after Henry Corbin recommended him in 1949, and wrote for the Antaios magazine (edited by Ernst Junger). In 1950, Eliade began attending Eranos conferences, meeting Jung, Olga Frobe-Kapteyn, Gershom Scholem and Paul Radin. He described Eranos as "one of the most creative cultural experiences of the modern Western world."  In October 1956, he moved to the United States, settling in Chicago the following year. He had been invited by Joachim Wach to give a series of lectures at Wach's home institution, the University of Chicago. Eliade and Wach are generally admitted to be the founders of the "Chicago school" that basically defined the study of religions for the second half of the 20th century. Upon Wach's death before the lectures were delivered, Eliade was appointed as his replacement, becoming, in 1964, the Sewell Avery Distinguished Service Professor of the History of Religions. Beginning in 1954, with the first edition of his volume on Eternal Return, Eliade also enjoyed commercial success: the book went through several editions under different titles, which sold over 100,000 copies.  In 1966, Mircea Eliade became a member of the American Academy of Arts and Sciences. He also worked as editor-in-chief of Macmillan Publishers' Encyclopedia of Religion, and, in 1968, lectured in religious history at the University of California, Santa Barbara. It was also during that period that Mircea Eliade completed his voluminous and influential History of Religious Ideas, which grouped together the overviews of his main original interpretations of religious history. He occasionally traveled out of the United States, such as attending the Congress for the History of Religions in Marburg (1960) and visits to Sweden and Norway in 1970.
