Max Frisch
Frisch's dramas up until the early 1960s are divided by the literary commentator into three groups: (1) the early wartime pieces, (2) the poetic plays such as "" ("Don Juan oder Die Liebe zur Geometrie") and (3) the dialectical pieces. It is above all with this third group, notably the parable "The Fire Raisers" (1953), identified by Frisch as a "lesson without teaching", and with "Andorra" (1961) that Frisch enjoyed the most success. Indeed, these two are among the most successful German language plays. The writer nevertheless remained dissatisfied because he believed they had been widely misunderstood. In an interview with Heinz Ludwig Arnold Frisch vigorously rejected their allegorical approach: "I have established only that when I apply the parable format, I am obliged to deliver a message that I actually do not have". After the 1960s Frisch moved away from the theatre. His late biographical plays "" ("Biografie: Ein Spiel") and "" were apolitical but they failed to match the public success of his earlier dramas. It was only shortly before his death that Frisch returned to the stage with a more political message, with "Jonas and his Veteran", a stage version of his arresting dialogue "Switzerland without an army? A Palaver".

Frisch himself took the view that the diary offered the prose format that corresponded with his natural approach to prose writing, something that he could "no more change than the shape of his nose". Attempts were nevertheless made by others to justify Frisch's choice of prose format. Frisch's friend and fellow-writer, Friedrich Dürrenmatt, explained that in "I'm Not Stiller" the "diary-narrative" approach enabled the author to participate as a character in his own novel without embarrassment. (The play focuses on the question of identity, which is a recurring theme in the work of Frisch.) More specifically, in the character of James Larkin White, the American who in reality is indistinguishable from Stiller himself, but who nevertheless vigorously denies being the same man, embodies the author, who in his work cannot fail to identify the character as himself, but is nevertheless required by the literary requirements of the narrative to conceal the fact. Rolf Keiser points out that the diary format enables Frisch most forcefully to demonstrate his familiar theme that thoughts are always based on one specific standpoint and its context; and that it can never be possible to present a comprehensive view of the world, nor even to define a single life, using language alone.
