Man in the Holocene Man in the Holocene (1979) is a novella by Swiss author Max Frisch, originally published in German in 1979, and in English in "The New Yorker" on May 19, 1980 (trans. Geoffrey Skelton). A distinctive feature of this book’s style is the use of reprinted cutouts which the protagonist, Mr. Geiser, removes from several encyclopedias, the bible and other books. It contains some autobiographical elements: Frisch at the time of the writing is about the same age as the protagonist, Mr. Geiser, and Frisch also had a house in the Tessin valley where the story is set.
