Heinz Ludwig Arnold, the journalist and editor from Göttingen who met Dürrenmatt in 1975, was probably more closely involved in the author's late work as a critic, part-time editor, and friend than anyone else. Arnold's collected essays and lectures, written with the most intimate knowledge of Dürrenmatt's writing, are among the best and most vivid texts ever written about Dürrenmatt, and particularly about the way his late work came into being. Heinz Ludwig Arnold is the editor of Dürrenmatt's Conversations 1961–1990, published by Diogenes in 1996.
