Problem: Background: Randi was born on August 7, 1928 in Toronto, Ontario, Canada, the son of Marie Alice (nee Paradis) and George Randall Zwinge. He has a younger brother and sister. He took up magic after seeing Harry Blackstone Sr. and reading conjuring books while spending 13 months in a body cast following a bicycle accident. He confounded doctors who expected he would never walk again.
Context: Randi is the author of ten books, among them Conjuring (1992), a biographical history of noted magicians. The book is subtitled Being a Definitive History of the Venerable Arts of Sorcery, Prestidigitation, Wizardry, Deception, & Chicanery and of the Mountebanks & Scoundrels Who have Perpetrated these Subterfuges on a Bewildered Public, in short, MAGIC! The book's cover says that it is by "James Randi, Esq., A Contrite Rascal Once Dedicated to these Wicked Practices but Now Almost Totally Reformed". The book selects the most influential magicians and tells some of their history, often in the context of strange deaths and careers on the road. This work expanded on Randi's second book titled Houdini, His Life and Art. This illustrated work was published in 1976 and was co-authored with Bert Sugar. It focuses on the professional and private life of Houdini.  Randi also wrote a children's book in 1989 titled The Magic World of the Amazing Randi, which introduced children to magic tricks. In addition to his magic books, he has written several educational works about paranormal and pseudoscientific claims. These include biographies of Uri Geller and Nostradamus as well as reference material on other major paranormal figures. He is currently working on A Magician in the Laboratory, which recounts his application of skepticism to science. He was a member of the all-male literary banqueting club the Trap Door Spiders, which served as the basis of his good friend Isaac Asimov's fictional group of mystery solvers, the Black Widowers.  Other books are Flim-Flam! (1982), The Faith Healers (1987), James Randi, Psychic Investigator (1991), Test Your ESP Potential (1982) and An Encyclopedia of Claims, Frauds, and Hoaxes of the Occult and Supernatural (1995).  Randi was a regular contributor to Skeptic magazine, penning the "'Twas Brillig..." column, and also served on its editorial board. He is also a frequent contributor to Skeptical Inquirer magazine, which is published by CSI, of which he is also a Fellow.

Problem: Background: Captain Marvel, also known as Shazam (), is a fictional superhero appearing in American comic books published by DC Comics. Artist C. C. Beck and writer Bill Parker created the character in 1939. Captain Marvel first appeared in Whiz Comics #2 (cover-dated Feb. 1940), published by Fawcett Comics.
Context: After the success of National Comics' new superhero characters Superman and Batman, Fawcett Publications started its own comics division in 1939, recruiting writer Bill Parker to create several hero characters for the first title in their line, tentatively titled Flash Comics. Besides penning stories featuring Ibis the Invincible, Spy Smasher, Golden Arrow, Lance O'Casey, Scoop Smith, and Dan Dare for the new book, Parker also wrote a story about a team of six superheroes, each possessing a special power granted to them by a mythological figure.  Fawcett Comics' executive director Ralph Daigh decided it would be best to combine the team of six into one hero who would embody all six powers. Parker responded by creating a character he called "Captain Thunder". Staff artist Charles Clarence "C. C." Beck was recruited to design and illustrate Parker's story, rendering it in a direct, somewhat cartoony style that became his trademark. "When Bill Parker and I went to work on Fawcett's first comic book in late 1939, we both saw how poorly written and illustrated the superhero comic books were," Beck told an interviewer. "We decided to give our reader a real comic book, drawn in comic-strip style and telling an imaginative story, based not on the hackneyed formulas of the pulp magazine, but going back to the old folk-tales and myths of classic times".  The first issue of the comic book, printed as both Flash Comics #1 and Thrill Comics #1, had a low-print run in the fall of 1939 as an ashcan copy created for advertising and trademark purposes. Shortly after its printing, however, Fawcett found it could not trademark "Captain Thunder", "Flash Comics", or "Thrill Comics", because all three names were already in use. Consequently, the book was renamed Whiz Comics, and Fawcett artist Pete Costanza suggested changing Captain Thunder's name to "Captain Marvelous", which the editors shortened to "Captain Marvel". The word balloons in the story were re-lettered to label the hero of the main story as "Captain Marvel". Whiz Comics #2 (cover-dated Feb. 1940) was published in late 1939.
