 Jacobi created an anti-Semitic cartoon lampooning Lion, playing on Lion's Jewish birth, changing "Jungensport in Feld und Wald" (youth sports in field and forest) to ""Judensport" in Wald und Feld" (Jews' sports in forest and field), and calling Scouting supporter General Baschwitz a "vain Jewish man".In 1913 Alexander Lion met Emmerich Teuber, an Austrian Scouting pioneer and later member of the International Committee of the World Organization of the Scout Movement, and the two Scout Leaders became friends.On the outbreak of the First World War, Lion became head physician at a field hospital, and worked to treat the wounded on the front lines, work for which he received the Prussian Iron Cross Class II.
