to Rome. From 1908 to 1913 the Hofer family lived in Paris, and in 1913 they moved to Berlin. During his residence in Paris, he was very influenced by Paul Cézanne and by Pablo Picasso, specially his early period. Since 1905, Hofer's paintings had been regularly shown at exhibitions. In 1908 he was represented at the exhibition of the "Berlin Secession", founded by Max Liebermann. In Berlin, Hofer became a member of the new "Freie Secession" in 1913 and was represented at its first exhibition in 1914, together with Max Liebermann, and German Expressionist painters Erich Heckel, Ernst Ludwig Kirchner, Max Pechstein and Karl Schmidt-Rottluff. Hofer traveled to India in 1910 and 1911. During the Summer of 1914, during a stay in the French seaside resort of Ambleteuse, the Hofers were surprised by the outbreak of the First World War and were interned because of their citizenship. Mathilde and the sons were eventually allowed to return to Germany at the end of 1914. Hofer was dismissed by the mediation of Reinhart in 1917, and moved to Switzerland, first to Churwalden, then to Zurich. After the end of the war, Hofer returned to his family in Berlin, in 1919. In 1920 he was appointed to the College of Fine Arts in Charlottenburg, and in 1921 he was appointed professor. The College of Fine Arts was merged in 1924 with the Arts and Crafts Museum to form the United State Schools of Free and Applied Arts.
