During his studies in Dresden, Kirchner met Fritz Bleyl, Erich Heckel and Karl Schmidt-Rottluff, which led to lively artistic collaborations and the founding of the artist group 'Die Brücke' in 1905. It's intention was "to attract all revolutionary and restless forces" (Schmidt-Rottluff). The big city was a major inspiration and influence on Kirchner's work. He found new subjects in nature and architecture and translated their shapes in his own way – simple, sharply outlined forms as well as expressive, vivid colour contrasts create the characteristic city scapes, that made Ernst Ludwig Kirchner one of the most influential German artists of the 20th century. The outbreak of the first world war marks a difficult period for Kirchner. His military service led to illness and long stays in hospitals. Nevertheless, Kirchner continued his artistic career and settled in Frauenkirch near Davos in 1917 after the war. The famous mountain landscapes und scenes of rural life emerge during this time period in the small village in Switzerland. Ernst Ludwig Kirchner worked until his suicide in 1938.
