The equivalent French term expérience de mort imminente (experience of imminent death) was proposed by French psychologist and epistemologist
Victor Egger as a result of discussions in the 1890s among philosophers and psychologists concerning climbers' stories of the panoramic life review during falls. In 1892 a series of subjective observations by workers falling from scaffolds, war soldiers who suffered injuries, climbers who had fallen from heights or other individuals who had come close to death (near drownings, accidents) was reported by Albert Heim. This was also the first time the phenomenon was described as clinical syndrome. In 1968 Celia Green published an analysis of 400 first-hand accounts of out-of-body experiences. This represented the first attempt to provide a taxonomy of such experiences, viewed simply as anomalous perceptual experiences, or hallucinations. In 1969, Swiss-American psychiatrist and pioneer in near-death studies Elisabeth Kubler-Ross published her groundbreaking book On Death and Dying: What the dying have to teach doctors, nurses, clergy, and their own families. These experiences were also popularized by the work of psychiatrist Raymond Moody, who in 1975 coined the term "near-death experience" (NDE) as an umbrella term for the different elements (out of body experiences, the "panoramic life review," the Light, the tunnel, or the border). The term "near-death experience" had already been used by John C. Lilly in 1972.
