authors like Hermann Hesse and Franz Kafka counted him among their favorite writers. Walser published numerous short stories in newspapers and magazines, many for instance in the Schaubühne. They became his trademark. The larger part of his work is composed of short stories – literary sketches that elude a ready categorization. Selections of these short stories were published in the volumes Aufsätze (1913) and Geschichten (1914). 1913–1929 In 1913, Walser returned to Switzerland. He lived for a short time with his sister Lisa in the mental home in Bellelay, where she worked as a teacher. There, he got to know Lisa Mermet, a washer-woman with whom he developed a close friendship. After a short stay with his father in Biel, he went to live in a mansard in the Biel hotel Blaues Kreuz. In 1914, his father died. In Biel, Walser wrote a number of shorter stories that appeared in newspapers and magazines in Germany and Switzerland and selections of which were published in Der Spaziergang (1917), Prosastücke (1917), Poetenleben (1918), Seeland (1919) and Die Rose (1925). Walser, who had always been an enthusiastic wanderer, began to take extended walks, often by night. In his stories from that period, texts written from the point of view of a wanderer walking through unfamiliar neighborhoods alternate with playful essays on writers and artists. During World War I, Walser repeatedly had to go into military service. At the end of 1916, his brother Ernst died after a time of mental illness in the Waldau mental home. In 1919, Walser's brother Hermann, geography professor in Bern, committed suicide. Walser himself became isolated in that time, when there was almost no communication with Germany because of the war. Even though he worked hard, he could barely support himself as a freelance writer. At the beginning of 1921, he moved to Bern in order to work at the public record office. He often changed lodgings and lived a very solitary life. During his time in Bern, Walser's style became more radical. In a more and more condensed form, he wrote "micrograms" ("Mikrogramme"), called thus because of his minuscule pencil hand that is very difficult to decipher. He wrote poems, prose, dramolettes and novels, including The Robber (Der Räuber). In these texts, his playful, subjective style moved toward a higher abstraction. Many texts of that time work on multiple levels – they can be read as naive-playful
