George Ivanovich Gurdjieff was born around 1866–1877 (accounts vary) in Alexandropol (now Gyumri, Armenia), then part of the Russian Empire, to a Greek father and Armenian mother. He grew up in Kars, a cosmopolitan border town where Greeks, Armenians, Russians and Turks mixed, and where he received an education that combined Orthodox Christian theology with exposure to multiple cultural and religious traditions.
As a young man, Gurdjieff travelled extensively — his own account, in Meetings with Remarkable Men, describes journeys through Central Asia, Egypt, Persia, Afghanistan, Tibet and India in search of esoteric knowledge. He claims to have encountered a series of remarkable teachers and hidden brotherhoods. None of these journeys can be independently verified, and historians have been unable to confirm the sources of the teaching he later transmitted. Whether the teaching came from a living tradition he discovered, from his own synthesis of available sources, or from some combination, remains genuinely unknown.
He appeared in Moscow and St Petersburg around 1912–1913, gathering a circle of students including the journalist and mathematician P.D. Ouspensky, who would become his most important early disciple and the most systematic expositor of his ideas. The Russian Revolution disrupted this circle; Gurdjieff led a group of followers on an extraordinary journey through the Caucasus during the civil war, eventually settling in Tiflis, then Constantinople, then Berlin and finally Paris, where he established the Institute for the Harmonious Development of Man at Fontainebleau in 1922.
At Fontainebleau, Gurdjieff developed his full teaching method — combining philosophical instruction, manual labour, sacred dances (the Movements), music and an intense interpersonal dynamic in which he deliberately provoked students to expose their mechanical reactivity. A serious car accident in 1924 nearly killed him; during his long recovery he began writing Beelzebub's Tales to His Grandson. He spent his remaining decades in Paris, teaching a small circle of students, until his death in 1949.
