After attending schools in several towns, as his family moved, and finishing Rygiškių Jonas High School in Marijampolė in 1934, he studied law at Vytautas Magnus University, Kaunas, and then drifted toward linguistics at the University of Grenoble, from which he graduated in 1939 with a paper on Franco-Provençal dialects.
In July 1940, he gave speeches urging Lithuanians to elect leaders who would vote in favor of annexation by the Soviet Union.
In October, he was discharged into the reserve, and he began teaching French, German, Lithuanian and humanities at schools in Šiauliai.
In March 1941, Greimas's friend, Vladas Pauža, a boy scout and fellow teacher, enlisted him in the Lithuanian Activist Front.
Meanwhile, during these traumatic deportations, Greimas had been mobilized as an army officer to write up the property of detained Lithuanians.
He grew close to life long liberal-minded friends Bronys Raila, Stasys Žakevičius-Žymantas, Jurgis Valiulis.
In 1944 he enrolled for graduate study at the Sorbonne in Paris and specialized in lexicography, namely taxonomies of exact, interrelated definitions.
[9] Greimas began his academic career as a teacher at a French Catholic boarding school for girls in Alexandria in Egypt,[5] where he would take part in a weekly discussion group of about a dozen European researchers that included a philosopher, a historian, and a sociologist.
In 1965 he became professor at the École des Hautes Études en Sciences Sociales (EHESS) in Paris, where he taught for almost 25 years.
Greimas died in 1992 in Paris, and was buried at his mother's resting place,[11] Petrašiūnai Cemetery in Kaunas, Lithuania.
[citation needed] During his decade in Alexandria, the discussions in his circle of friends helped broaden his interests.
The topics included Greimas's early influences – the works of the founder of structural linguistics Ferdinand de Saussure and his follower, Danish linguist Louis Hjelmslev, the initiator of comparative mythology Georges Dumézil, the structural anthropologist Claude Lévi-Strauss, the Russian specialist in fairy tales Vladimir Propp, the researcher into the aesthetics of theater Étienne Souriau, the phenomenologists Edmund Husserl and Maurice Merleau-Ponty, the psychoanalyst Gaston Bachelard, and the novelist and art historian André Malraux.
Greimas begins by positing the existence of a semantic universe that he defined as the sum of all possible meanings that can be produced by the value systems of the entire culture of an ethno-linguistic community.
He based his work on the methods of Vladimir Propp, Georges Dumézil, Claude Lévi-Strauss, and Marcel Detienne.
He published the results in Apie dievus ir žmones: lietuvių mitologijos studijos (Of Gods and Men: Studies in Lithuanian Mythology) 1979, and Tautos atminties beieškant (In Search of National Memory) 1990.
