Question: Which aeronautical engineer wrote the 1942 novel, Pied Piper? 
Context: The Changin' Times were an American songwriting and performing duo (Artie Kornfeld and Steve Duboff).  They achieved success with "The Pied Piper" in 1965, and songs for other artists.  "The Pied Piper", and their other songs like "Free Spirit" were covered by Crispian St. Peters. Ratcatcher's Day, Rat-catcher's Day or Rat Catcher's Day is celebrated on 26 June or 22 July, commemorating the myth of the Pied Piper of Hamelin.  The town of Hamelin in Germany uses the June date and the term "Pied Piper Day".  The confusion of dates is because the Brothers Grimm cite 26 June 1284 as the date the Pied Piper led the children out of the town, while the poem by Robert Browning gives it as 22 July 1376.  It is a holiday remembering rat-catchers, similar to Secretary's Day. This is a list of literary accounts of the Pied Piper, that is, of tellings or retellings of the full story of the Pied Piper of Hamelin.  For briefer allusions to the Pied Piper, in literature and other media, see Pied Piper of Hamelin in popular culture.

His crimes were profiled by journalist Don Moser in his article "The Pied Piper of Tucson", featured in the March 4, 1966 issue of "Life" magazine and are the basis for "Where Are You Going, Where Have You Been?

Richard Cummings is an author, playwright, theorist and critic.  His biography of Allard Lowenstein, "The Pied Piper – Allard Lowenstein and the Liberal Dream," alleges that Lowenstein worked for the CIA.  Cummings' biography was met with some controversy; in a "New York Times" review, entitled "His Innocence Proves His Guilt," written by Ronald Radosh, the reviewer judges that Cummings in that book has offered "a conspiracy theory marked by guilt by association and a failure to examine evidence that contradicts his own views."  Radosh notes further that "Lowenstein's friends and family were so upset about the allegations in The Pied Piper that they have gone to great lengths to gather affidavits from scores of individuals mentioned or interviewed by Mr. Cummings, affidavits that dispute the author's research and conclusions."  In the second edition of "The Pied Piper" (paperback) Cummings quotes from Lowenstein's CIA file which clearly indicates that Lowenstein was recruited through the CIA in 1962 and that they planned to use him on an "ad hoc" basis.  The CIA file also indicates that Lowenstein himself said that he had already done some work for the CIA. Pied Piper is a novel by Nevil Shute, first published in 1942.
