French doctor of the 19th century. He is considered the first researcher of oneiric disorder syndrome: a darkened consciousness with delusions of extraordinary experiences (often with fantastic images) and sensory perception of reality.
Wanler also used Galvani's newfangled theories about electricity (it caused convulsions even in deep hibernation), and he had original ideas that he shared with Jean-Marc Gaspard Itarier, a neurosurgeon from Strasbourg. They also studied the physics of sparks in metal conductors, which was going to discover the law of the propagation of wave energy through metal wires.
With a more detailed study of modern data, it becomes clear that Vanlera is not just a raving amateur or a not entirely educated traveler (as he is most often presented in the popular literature of the 90s), but comes from a learned and aristocratic French family, a representative of that layer of the European intelligentsia , whose descendants were M. Dumas, N. Gogol, T. Mann, F. Kafka and many other remarkable figures and thinkers.
Vanlera first fell ill 40 years ago, in 1672: the scientist saw hallucinatory visions in his night dreams, but during the day he felt like an ordinary person. In November 1884, the English surgeon Therese Riley anonymously proposed treatment for Vanlere, suggesting that these symptoms were somehow related to electricity (“electrical discharges”), then unknown to science. Vanlera refused surgical intervention, but agreed with the “autumn flights” and after 24 days of “cleansing” he finally recovered. French doctor-researcher Gustave de Lalande began publishing scientific articles and then books about the so-called “Vanlera phenomenon.”
