The Wizard of the Emerald City: The Wizard of the Emerald City (Russian: Волшебник Изумрудного Города ) is a 1939 children's novel by Russian writer Alexander Melentyevich Volkov.  The book is a re-narration of L. Frank Baum's "The Wonderful Wizard of Oz".  Baum's name is sometimes credited in the book (in the appendix by Volkov, which is found in some editions, where Volkov describes the origins of his book).  The names of most characters are changed, some elements of Baum's novel are removed, and some new elements are added.  The book was illustrated by Leonid Vladimirski in 1959 and became quite popular in the 1960s, leading to five sequels: "Urfin Jus and his Wooden Soldiers" (1963), "The Seven Underground Kings" (1964), "The Fiery God of the Marrans" (1968), "The Yellow Fog" (1970), and "The Secret of the Abandoned Castle" (1975, published in 1982).  These sequels were written by Volkov himself and are not based on Baum's plot elements, although we do encounter the powder of life, a character called Charlie Black who is not unlike Cap'n Bill, intelligent foxes, and the use of a Sandboat similar to Johnny Dooit's, albeit with wheels.

Jules Gervais-Courtellemont: Jules Gervais-Courtellemont (1863–1931) was a French photographer who was famous for taking color autochromes during World War I.  He was born in the province of Seine-et-Marne, near Paris, but grew up in Algeria, where he developed a passion for the pre-colonial Orient and devoted most of his professional career in search of the exotic.  In 1894 converted to Islam prior to making a pilgrimage to Mecca.  Images collected in Turkey, Palestine, Egypt, Tunisia, Spain, India, Morocco and China formed the basis for his popular illustrated lectures, which he illustrated with lantern slides.  With the outbreak of World War I, Courtellemont returned to his home province to record the war.  After the war, Courtellemont began working for an American publication.  He eventually became a photographer for "National Geographic".  In 1911, Courtellemont opened the "Palais de l'autochromie" in Paris, which comprised an exhibition hall, studio, laboratory, and lecture hall with a seating capacity of 250.  It was in this hall that Courtellemont would project his autochromes both of the Orient and, after 1914, of the war, particularly the Marne battlefields.  These lectures proved to be so popular that Courtellemont issued a twelve-part series later bound in book form called "The Battle of Marne" and later a four-part series entitled "The Battle of Verdun".  These are the first books ever published in color on war.  Between 1923 and 1925 he wrote a three-volume work entitled "La Civilisation – Histoire sociale de l'humanité", illustrated with his photographs.  He was a lifelong friend of the novelist, Orientalist and photographer Pierre Loti.  While over 5,500 Gervais-Courtellemont autochromes survive in various institutional collections, his work in private hands is quite rare and sought after.  Courtellemon died in 1931.  His German counterpart is Hans Hildenbrand.
