Harry Stephen Patrick Child (born Harry Stephen Patrick Chesley) (May 23, 1905 – November 8, 1972)
Skinny Legs and All, novelist Tom Robbins' fifth book, was published in 1990 by Bantam Books.
 As with all of Robbins' novels, it weaves disparate and seemingly unrelated themes into a single narrative.
Even Cowgirls Get the Blues is a 1993 American romantic comedy-drama film based on Tom Robbins' 1976 novel of the same name.
 The film was directed by Gus Van Sant (credited as Gus Van Sant, Jr.) and starred an ensemble cast led by Uma Thurman, Lorraine Bracco, Angie Dickinson, Noriyuki "Pat" Morita, Keanu Reeves, John Hurt, and Rain Phoenix.
 Robbins himself was the narrator.
 The soundtrack was sung entirely by k.d. lang.
 The film was dedicated to the late River Phoenix.
The Mysterious Mr. Wong is a tongue-in-cheek 1934 mystery film starring Bela Lugosi as a powerful Fu Manchu type criminal mastermind of the Chinatown underworld, and Wallace Ford as a wisecracking reporter.
 The film is based on Harry Stephen Keeler's 1928 short story "The Strange Adventure of the Twelve Coins of Confucius" one of three stories in Keeler's book "Sing Sing Nights".
 Despite the name of the title character and being directed by William Nigh, it has no relation to Monogram Pictures later Mr Wong film series.
 The character of Mr. Wong does not appear in the original story.
Harry Stephen Keeler (November 3, 1890 – January 22, 1967) was a prolific but little-known American author of mysteries and science fiction.
Jitterbug Perfume is Tom Robbins' fourth novel and was listed on the "New York Times" Best Seller list in 1985.
 It is widely considered a cult classic and one of the "Best books of the 20th century".
 The book follows two interweaving storylines, one in Ancient Eurasia and one in the present-day.
 Darkly humorous and "presented in an idiosyncratic fictional style", the story connects dueling perfumers in Seattle, Paris and New Orleans to a bottle of incomparable perfume created by two unlikely but defiant lovers of the past who seek immortality.
 Orchestrated by a mysterious Irish philosopher, the past and the present collide when the characters come together and discover the unexpected path to life-everlasting.
 The book was first published in 1984 by Bantam Books and later published by Random House.
