Question: Were Friedrich Dürrenmatt and Henry Roth both writers?

full_context: Document 1: Portnoy's Complaint: Portnoy's Complaint is a 1969 American novel that turned its author Philip Roth into a major celebrity, sparking a storm of controversy over its explicit and candid treatment of sexuality, including detailed depictions of masturbation using various props including a piece of liver. The novel tells the humorous monologue of "a lust-ridden, mother-addicted young Jewish bachelor," who confesses to his psychoanalyst in "intimate, shameful detail, and coarse, abusive language." Many of its characteristics (comedic prose; themes of sexual desire and sexual frustration; a self-conscious literariness) went on to become Roth trademarks.
Document 2: The Judge and His Hangman: The Judge and His Hangman (German: Der Richter und sein Henker ) is a 1950 novel by the Swiss writer Friedrich Dürrenmatt. It was first published in English in 1954, in a translation by Cyrus Brooks and later in a translation by Therese Pol. A new translation by Joel Agee appeared in 2006, published together with it sequel "Suspicion", as "The Inspector Bärlach Mysteries," with a foreword by Sven Birkerts. Together with Dürrenmatt's "", these stories are considered classics of crime fiction, fusing existential philosophy and the detective genre.

In his time he was "arguably the most widely performed contemporary playwright in world theatre". Much of his dramatic work depends on improvisation and comprises the recovery of "illegitimate" forms of theatre, such as those performed by "giullari" (medieval strolling players) and, more famously, the ancient Italian style of "commedia dell'arte".

It belongs to the most important works of Dürrenmatt and is a classic among the surrealistic short stories. With the beginning of the story, Dürrenmatt parodies Thomas Mann. The first sentence is very long and nested. Furthermore, Dürrenmatts student is in a train and likes cigars – just like the young man in The Magic Mountain (Der Zauberberg).

It was then performed in Chile, Israel, and New York. The play was adapted into a 1961 film with the same title.

In the 21st century, publications in English of "Radetzky March" and of collections of his journalism from Berlin and Paris created a revival of interest in Roth.

He was known for breaking with existing literary forms, developing a new sort of semi-autobiographical novel that blended character study, social criticism, philosophical reflection, explicit language, sex, surrealist free association, and mysticism. His most characteristic works of this kind are "Tropic of Capricorn", The Colossus of Maroussi, The Time of the Assassins, and "The Books in My Life", many of which are based on his experiences in New York and Paris (some of which were banned in the United States until 1961), adding Big Sur and the Oranges of Heronymous Bosch while finally residing in Big Sur, California. He also wrote travel memoirs and literary criticism, and painted watercolors.

In addition, the book contains a discussion with Mary McCarthy about Roth's novel "The Counterlife" and a "New Yorker" essay on Saul Bellow. Roth's trip to Israel to interview Appelfeld inspired his novel "Operation Shylock".
Document 14: The Pledge: Requiem for the Detective Novel: The Pledge (German: "Das Versprechen") is a crime novella by Swiss author Friedrich Dürrenmatt, published in 1958, after Dürrenmatt thought that his previous movie script, "Es geschah am hellichten Tag" ("It happened in broad daylight") did not have a realistic ending. That made-for-television story had demanded an ending in line with that of a typical detective story. Dürrenmatt, however, was a critic of that genre of literature, and thus he set out to write "Das Versprechen" as an expression of that criticism. Although it has been absent from some subsequent editions of the novella, the title of the original edition included the telling subtitle Requiem for the Detective Novel (German: "Requiem auf den Kriminalroman").

He was the son of Henry James, Sr. and the brother of renowned philosopher and psychologist William James and diarist Alice James.
