Der Wanderer
Walter Flex, who is best known as the author of the war poem "Wildgänse rauschen durch die Nacht" and the novella "Der Wanderer zwischen Beiden Welten", was a native of Eisenach, in the Grand Duchy of Saxe-Weimar-Eisenach, and had attended the University of Erlangen. At the outbreak of the war, Flex was working as a private tutor to a family from the German nobility. Despite weak ligaments in his right hand, Flex immediately volunteered for the Imperial German Army.
