Sir John Falstaff is a fictional character who is mentioned in five plays by William Shakespeare and appears on stage in three of them.
 His significance as a fully developed character in Shakespeare is primarily formed in the plays "Henry IV, Part 1" and "Part 2", where he is a companion to Prince Hal, the future King Henry V.
 A notable eulogy for Falstaff is presented in Act II, Scene III of "Henry V", where Falstaff does not appear as a character on stage, as enacted by Mistress Quickly in terms that some scholars have ascribed to Plato's description of the death of Socrates after drinking hemlock.
 By comparison, in "The Merry Wives of Windsor", Falstaff is presented by Shakespeare as the buffoonish suitor of two married women.
Raggedy Ann is a character created by American writer Johnny Gruelle (1880–1938) that appeared in a series of books he wrote and illustrated for young children.
 Raggedy Ann is a rag doll with red yarn for hair and has a triangle nose.
 Johnny Gruelle received US Patent D47789 for his Raggedy Ann doll on September 7, 1915.
 The character was created in 1915 as a doll, and was introduced to the public in the 1918 book "Raggedy Ann Stories".
 When a doll was marketed with the book, the concept had great success.
 A sequel, "Raggedy Andy Stories" (1920), introduced the character of her brother, Raggedy Andy.
Felix Leiter is a fictional character created by Ian Fleming in the "James Bond" series.
 The character is an operative for the CIA and Bond's friend.
 After losing a leg and his hand to a shark attack, Leiter joined the Pinkerton Detective Agency.
 The name "Felix" comes from the middle name of Fleming's friend Ivar Bryce, while the name "Leiter" was the surname of Fleming's friend Marion Oates Leiter Charles, then wife of Thomas Leiter.
Spike, played by James Marsters, is a fictional character created by Joss Whedon for the television series "Buffy the Vampire Slayer" and "Angel".
 Spike is a vampire and played various roles on the shows, including villain, anti-hero, Trickster and lover.
 For Marsters, the role as Spike began a career in science fiction television, becoming "the obvious go-to guy for US cult [television]".
 For creator Whedon, Spike is the "most fully developed" of his characters.
 The character was intended to be a brief villain, with Whedon originally adamant to not have another major "romantic vampire" character like Angel.
 Marsters says "Spike was supposed to be dirty and evil, punk rock, and then dead."
 However, the character ended up staying for the second season, and then returning in the fourth to replace Cordelia as "the character who told Buffy she was stupid and about to die."
Commander James Bond, CMG, RNVR, is a fictional character created by British journalist and novelist Ian Fleming in 1953.
 He is the protagonist of the "James Bond" series of novels, films, comics and video games.
 Fleming wrote twelve Bond novels and two short story collections.
 His final two books—"The Man with the Golden Gun" (1965) and "Octopussy and The Living Daylights" (1966)—were published posthumously.
Oskar Rescher (October 1, 1884 – March 26, 1972), aka Osman Reşer, was a prolific German-Turkish scholar in Arabic, Persian, and Turkish literature who specialized in pre-Islamic Arabic poetry and Ottoman studies.
 In 1903 he began to study law in Munich but soon changed to Oriental languages.
 After receiving his doctorate at Berlin in 1909 with a dissertation on the Arab grammarian Ibn Jinni he moved to Istanbul to work in the libraries there.
 During World War I he served in the German Army as censor for Arabic prisoner of war correspondence.
 After the war, he moved to Breslau and received his "Habilitation" and "venia legendi" (the right to hold lectures at a German university) from the University of Breslau.
 In 1925 he began teaching as professor (without full chair) at Breslau, but in 1928 he took a long-term leave and returned to Turkey.
 He left Breslau "for reasons that can no longer be determined but he evidently did so with resentment" (Berthold Spuler).
 Rescher also relinquished his membership in the Deutsche Morgenländische Gesellschaft (DMG), the society of Oriental scholars in Germany.
 In due course he acculturated to the Turkish locale, changing the spelling of his name, and converting to Islam.
 For many years he was a staff member of the Islamic Institute of the University of Istanbul.
 There he spent the rest of his life, producing numerous scholarly studies and translating many texts into German.
 (He himself also wrote Oriental-style poetry in German.)
 Apart from keeping close contact with his Turkish colleagues and with Helmut Ritter, who was between 1926 and 1949 a semi-official representative of the DMG in Istanbul, Rescher lived a solitary life in his Istanbul house overlooking the Bosphorus, accompanied by many cats.
James Arnold Hepokoski (born 1946) is an American musicologist.
 He earned his Masters and PhD in Music History from Harvard University, studying with David G. Hughes, John M. Ward, Oliver Strunk and Christoph Wolff, earning his doctorate in 1979 with a dissertation on Giuseppe Verdi's "Falstaff".
 Since 1999 he has been Professor of Music at Yale University; earlier he taught at the University of Minnesota and at Oberlin College.
Captain Isaac Biddlecomb is a fictional character created by maritime writer/novelist James L. Nelson.
 He is a merchant captain whose smuggling occupation and later participation in the American Revolution has made him the pride of the American colonies.
 After the first version of "By Force of Arms" was written, the author planned to change his name to Nathaniel, but decided that Isaac was too deeply engrained into his character.
 Instead, he used that name for Biddlecomb's faithful boatswain, and later, for his own son.
Nyoka the Jungle Girl is a fictional character created for the screen in the 1941 serial "Jungle Girl", starring Frances Gifford as Nyoka Meredith.
 The character of Nyoka is often described as having been created by Edgar Rice Burroughs; however, although the serial was officially based on Burroughs' story "Jungle Girl" (first appearing in the pulp magazine, "Blue Book", and later published as a novel), there is no character named Nyoka and no Nyoka-like character in the original story.
 The movie's credits list Burroughs along with six other writers, but his input on creating the film character was obviously minimal, because the studio later was able to use the name "Nyoka" in a sequel without crediting Burroughs at all.
 After the initial film, Nyoka appeared in comic books published by Fawcett, Charlton, and AC Comics.
Lobby Lud is a fictional character created in August 1927 by the "Westminster Gazette", a British newspaper, now defunct.
 The character was used in readers' prize competitions during the summer period.
 Anonymous employees visited seaside resorts and afterwards wrote down a detailed description of the town they visited, without giving away its name.
 They also described a person they happened to see that day and declared him to be the "Lobby Lud" of that issue.
 Readers were given a pass phrase and had to try and guess both the location and the person described by the reporters.
 Anyone carrying the newspaper could challenge Lobby Lud with the phrase and receive five pounds (about £ in 2017 ).
