Question: Are both Charles Palliser and Tom Stoppard internationally known?

full_context: Document 1: Charles Palliser: Charles Palliser (born December 11, 1947 in Holyoke, Massachusetts) is a best-selling novelist, American-born but British-based. His most well-known novel, "The Quincunx", has sold over a million copies internationally. He is the elder brother of the late author and freelance journalist Marcus Palliser.
Document 2: Dogg's Hamlet, Cahoot's Macbeth: Dogg's Hamlet, Cahoot's Macbeth are two plays by Tom Stoppard, written to be performed together. This was not the first time that Stoppard had made use of Shakespearian texts in his own plays or even the first time he had used "Hamlet" although the context is far different from that of his earlier "Rosencrantz and Guildenstern are Dead". Stoppard would return to the theme of artistic dissent against the Communist Party of Czechoslovakia in "Rock 'n' Roll".
Document 3: Charles Lamb: Charles Lamb (10 February 1775 – 27 December 1834) was an English essayist, poet, and antiquarian, best known for his "Essays of Elia" and for the children's book "Tales from Shakespeare", co-authored with his sister, Mary Lamb (1764–1847).
Document 4: Rosencrantz and Guildenstern Are Dead: Rosencrantz and Guildenstern Are Dead, often referred to as just Rosencrantz and Guildenstern, is an absurdist, existentialist tragicomedy by Tom Stoppard, first staged at the Edinburgh Festival Fringe in 1966. The play expands upon the exploits of two minor characters from Shakespeare's "Hamlet", the courtiers Rosencrantz and Guildenstern. The action of Stoppard's play takes place mainly "in the wings" of Shakespeare's, with brief appearances of major characters from "Hamlet" who enact fragments of the original's scenes. Between these episodes the two protagonists voice their confusion at the progress of events occurring onstage without them in "Hamlet", of which they have no direct knowledge.
Document 5: The Quincunx: The Quincunx (The Inheritance of John Huffam) is the epic first novel of Charles Palliser. It takes the form of a Dickensian mystery set in early 19th century England, but Palliser has added the modern attributes of an ambiguous plot and unreliable narrators. Many of the puzzles that are apparently solved in the story have an alternative solution in the subtext.
Document 6: George Bernard Shaw: George Bernard Shaw ( ; 26 July 1856 – 2 November 1950), known at his insistence simply as Bernard Shaw, was an Irish playwright, critic and polemicist whose influence on Western theatre, culture and politics extended from the 1880s to his death and beyond. He wrote more than sixty plays, including major works such as "Man and Superman" (1902), "Pygmalion" (1912)" and Saint Joan" (1923). With a range incorporating both contemporary satire and historical allegory, Shaw became the leading dramatist of his generation, and in 1925 was awarded the Nobel Prize in Literature.
Document 7: Undiscovered Country: Undiscovered Country is a 1979 Tom Stoppard play first produced at the Olivier Theatre in London. The play is an adaptation of "Das Weite Land" by the Austrian playwright Arthur Schnitzler, which focuses on 1890s Viennese society, demonstrating the effects of upper class codes of behavior on human relationships. The main character is a self-made businessman named Friedrich Hofreiter who manages to be both charming and chauvinistic. Stoppard's alterations to the play consist of adding humor while lessening the melodrama. The title of the play is a reference to the concept of the afterlife as the "undiscovered country" from the "To be, or not to be" soliloquy in "Hamlet".
Document 8: Charles Goodall (poet): Charles Goodall (1671—May 11, 1689) is a minor English poet. A student of Eton College and then Merton College, Oxford, he wrote a number of romantic and erotic poems referring to male students at said colleges. In 1689, the year of his death, he put together a collection entitled "Poems and Translations" which contains 33 poems with male-male subject matter, eleven regarding women, and 13 to a mistress named 'Idera' (considered probably imaginary). A number of the homoerotic poems have been rewritten to remove the same-sex subject matter.

He has also written philosophical works, such as "The Human Touch: Our Part in the Creation of the Universe" (2006).

Document 15: List of prolific writers: Some writers have had prolific careers with hundreds of their works being published. While some best-selling authors have written a small number of books that have sold millions of copies, others have had lengthy careers and maintained a high level of output year after year. Dame Agatha Christie, the most-published novelist in history, is estimated to have sold 4 billion books, having written 69 novels and 19 plays. Her works were published between 1920 and 1976, equating to around three publications every two years. Dame Barbara Cartland has also sold millions of copies of her books but wrote many more than Christie. She spent 80 years as a novelist with 722 books published, averaging one book released every 40 days of her career. While Cartland wrote a significant number of full-length novels, other authors have been published many more times but have specialised in short stories. Spanish author Corín Tellado wrote over 5,000 novellas, selling 400 million copies of her books.
