Question: Douglas Adams and P. G. Wodehouse, are of which nationality?
Context: Black Cinderella Two Goes East (sometimes referred to as Black Cinderella II Goes East) was a radio pantomime broadcast on BBC Radio 2 on 25 December 1978.  The programme is notable for being one of only a few radio programmes (co)-produced by Douglas Adams while he was employed by the BBC as a radio producer, also for giving a significant role to a serving politician, John Pardoe.  The hour-long programme was written by Clive Anderson and Rory McGrath and was co-produced by Douglas Adams and John Lloyd. Aaron "Geek in the City" Duran (born 1976 in California) is an American writer and media producer in Portland, Oregon, of Mexican and Italian descent.  He is the host of "Geek in the City Radio" (Formerly "Film Fever Radio") (alongside co-host Scott Dally), webmaster of GeekInTheCity.com, and a regular guest on the "cortandfatboy" (hosted by Cort Webber and Bobby Roberts) and "The Rick Emerson Show".  For several years, he was also one of the producers of Ground Zero Radio with Clyde Lewis.  Duran organized a failed effort in 2008 to rename Portland's "42nd Avenue" to "Douglas Adams Boulevard" in honor of science fiction author Douglas Adams. "The Private Life of Genghis Khan" is a short story written by Douglas Adams and Graham Chapman.  It is based in part on a sketch devised by Graham Chapman, and written by Chapman and Adams for the 1975 TV show pilot "Out of the Trees".  It appears in "The Utterly Utterly Merry Comic Relief Christmas Book" and some versions of "The Salmon of Doubt".  It is also available on Douglas Adams' website. Hyperland is a 50-minute-long documentary film about hypertext and surrounding technologies.  It was written by Douglas Adams and produced and directed by Max Whitby for BBC Two in 1990.  It stars Douglas Adams as a computer user and Tom Baker, with whom Adams had already worked on "Doctor Who", as a personification of a software agent. Douglas Noel Adams (11 March 1952 – 11 May 2001) was an English author, scriptwriter, essayist, humorist, satirist and dramatist. Aunts Aren't Gentlemen is a comic novel by P. G. Wodehouse, first published in the United Kingdom in October 1974 by Barrie & Jenkins, London, and in the United States under the title "The Cat-nappers" on 14 April 1975 by Simon & Schuster, New York.  It was the last novel to feature some of Wodehouse's best known characters, Bertie Wooster and his resourceful valet Jeeves, and the last novel fully completed by Wodehouse before his death. Douglas Adams at the BBC is a three CD set released by BBC Audio in 2004 (ISBN  ).  By using extracts from many radio and TV productions, the three discs cover Douglas Adams's association with BBC Radio and TV from 1974 to 2001, and also include tributes to Adams that were transmitted between 2001 and 2003.  Subjects are covered in an A-Z format (thus becoming an "A-Z of Douglas Adams").  Linking narration on all three discs is provided by Simon Jones.  Several of the sketches, many of which are included for the first time since their original transmissions, had been discussed in biographies of Adams (e.g. "Don't Panic" by Neil Gaiman and "Wish You Were Here" by Nick Webb).  In addition, the complete script for "The Lost Hitchhiker Sketch" appears in the 25th anniversary edition of "".  Disc one covers subjects A to G, disc two covers subjects H to P, and disc three covers subjects Q to Z. Sir Pelham Grenville Wodehouse {'1': ", '2': ", '3': ", '4': "} ( ; 15 October 188114 February 1975) was an English author and one of the most widely read humorists of the 20th century.  Born in Guildford, the son of a British magistrate based in Hong Kong, Wodehouse spent happy teenage years at Dulwich College, to which he remained devoted all his life.  After leaving school he was employed by a bank but disliked the work and turned to writing in his spare time.  His early novels were mostly school stories, but he later switched to comic fiction, creating several regular characters who became familiar to the public over the years.  They include the jolly gentleman of leisure Bertie Wooster and his sagacious valet, Jeeves; the immaculate and loquacious Psmith; Lord Emsworth and the Blandings Castle set; the Oldest Member, with stories about golf; and Mr Mulliner, with tall tales on subjects ranging from bibulous bishops to megalomaniac movie moguls. Performing Flea is a non-fiction book, consisting of a series of letters written by P. G. Wodehouse to William Townend, a friend of Wodehouse's since their schooldays together at Dulwich College.  It was originally published in the United Kingdom on 9 October 1953 by Herbert Jenkins, London.  The title alludes to a disparaging comment by the playwright Seán O'Casey, who, in a letter to "The Daily Telegraph" in July 1941, referring to Wodehouse's radio broadcasts from Berlin, wrote that "If England has any dignity left in the way of literature, she will forget for ever the pitiful antics of English literature's performing flea". The Hitchhiker's Guide to the Future was a four-part radio series hosted by Douglas Adams.  It was first broadcast on BBC Radio 4 in October 2000, and repeated in April and May 2001, and September 2014.  Because the radio series turned out to be Adams's final project for the BBC before his death (a week after the first broadcast of the final episode), all four episodes are still available for download from the Radio 4 website.  Extracts from the four programmes are also available for listening within the "Douglas Adams at the BBC" collection.
