Murders in the Rue Morgue (1932 film) the Rue Morgue" were disappointing, and Lugosi's original Universal contract for "Dracula" was not extended. Today, however, the film is generally well-regarded by critics and is considered a cult classic. In Paris in 1845, a mad scientist, Dr. Mirakle (Bela Lugosi), abducts young women and injects them with ape blood, in order to create a mate for his talking sideshow ape Erik (Charles Gemora, the gorilla performer). Young Pierre Dupin, a young naive medical student and detective (Leon Ames — credited as Leon Waycoff — in the role of Poe's standard detective icon, C. Auguste Dupin), his fiancée Camille L'Espanaye
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
