in 1915 as a military medic. In 1915, the couple had a son, Alexandre Minkowski, later a pioneer of French neonatology and father of the noted orchestra conductor, Marc Minkowski, followed in 1918 by a daughter, Jeannine, a lawyer. In the war he saw action at the Battle of the Somme and the Battle of Verdun, where his bravery earned him several citations and military decorations, including the Croix de Guerre. He became an officer of the Legion of Honour and obtained French nationality. In France Minkowski came under the influence of the famous French philosopher Henri Bergson, who critiqued standard scientific views of time and of life. Minkowski was convinced that psychopathology should be closer to philosophy and closer to individual philosophers' views. For Minkowski, Bergson was the paradigmatic philosopher. After the war he said: "During the war we were waiting for peace, hoping to take up again the life that we had abandoned. In reality, a new period began, a period of difficulties and deceptions, of setbacks and painful, often fruitless efforts to adapt oneself to new problems of existence. The calm propitious to philosophic thought was far from reborn. Long, arid, and somber years followed the war. My work lay dormant at the bottom of my drawer". After World War I, when his enlistment came to an end, he adopted French nationality. The family moved again to Paris permanently and Minkowski returned to medicine and partially abandoned his philosophical pursuits. He worked on the perception of time as a vector in psychopathology, drawing heavily on his unpublished work on Bergson, whom he had known personally. In 1925 he became one of the co-founders of a movement and a French journal in psychiatry, known as "L'Évolution psychiatrique" – "Psychiatric Evolution". "L'Évolution psychiatrique", which introduced the work of Eugen Bleuler and several other psychiatrists, such as Karl Jaspers and Ludwig Binswanger. Directors of "l'Ėvolution psychiatrique" were A. Hesnard and R. Laforgue. Original works and critical studies in the journal have been made by messieurs R. Allendy, A. Borel, A. Ceillier, H. Claude, H. Codet, J. Damourette, A. Hesnard, R. Laforgue, Mme F. Minkowska, E. Minkowski, É Pichon, Robin, R. de Saussure, Schiff and J. Vinchon. In 1925 Minkowski contributed articles to the first volume of "L'Ėvolution psychiatrique" : "La Génèse de la Notion de Schizophrénie et ses Caractères Essentiels" – "Genesis of the Notion of Schizophrenia and its Essential
