He studied at the Lycée Lakanal in Sceaux, Hauts-de-Seine, near Paris, where he prepared for the entrance examination to the École Normale Supérieure, but without success. At the Lycée Lakanal, he met Jacques Rivière, and the two became close friends.
Fournier went on to study at the merchant marine school in Brest. In 1909, Jacques Rivière married Fournier's younger sister Isabelle.
Abandoning his studies in 1907, from 1908 to 1909 Fournier did his military service. Around that time, he published some essays, poems and stories which were later collected and re-published under the title “Miracles”.
In early 1914, Fournier started work on a second novel – “Colombe Blanchet” - but it remained unfinished when he joined the Army as a Lieutenant in August 1914. Fournier was killed fighting near Vaux-lès-Palameix (Meuse) one month later, on 22nd September 1914. His body remained unidentified until 1991.
Alain-Fournier wrote the novel “Le Grand Meaulnes”, published in 1913, which I read at school. The book has been made into a film twice and is considered a classic of French literature. The story is partly based on his childhood unfolding in an atmosphere of mystical unreality beyond which the world of adulthood is perceived.
I remember when Alain-Fournier’s body was discovered and re-burried in the cemetery of Saint-Remy-la-Calonne, Meuse, Lorraine, France.
