C. Auguste Dupin of their around-the-world adventure. A Pierre Dupin appears in Universal Pictures' 1932 horror-mystery film "Murders in the Rue Morgue". "The Mystery of Marie Roget" was also filmed in 1942. Dupin (played by Joseph Cotten) is a character in the 1951 Fletcher Markle film "The Man with a Cloak". Dupin's true identity is revealed at the end of the film to be Poe himself.

Commonly known as the "Bat Computer," it is originally nicknamed "Dupin," after Batman's "hero."
Dupin indicatrix Dupin indicatrix In differential geometry, the Dupin indicatrix is a method for characterising the local shape of a surface. Draw a plane parallel to the tangent plane and a small distance away from it. Consider the intersection of the surface with this plane. The shape of the intersection is related to the Gaussian curvature. The Dupin indicatrix is the result of the limiting process as the plane approaches the tangent plane. The indicatrix was invented by Charles Dupin. For elliptical points where the Gaussian curvature is positive the intersection will either be empty or form a closed curve. In the
