Geometric Model, L. Brill No. 147. Ser. 8 No. 21, Minimal Surface (Enneper's Surface)


This white plaster model of a minimal surface has a rectangular base and a curved surface with a hole in the middle. A black metal support protrudes on the right but supports nothing (the top section of the model is missing). A net of lines is indicated on the surface. A paper tag reads: 147. Another paper tag reads: Minimalfläche 9. Ordn [. . .] (/) Verl. v. L. Brill. 8. Ser. N [. . .].

This surface was discussed by Enneper in a publications of 1864 and 1871. It is one of a series of models desgned at the technical high school in Munich and fist published by Brill in 1882. The designer was G. Herting.

This example of the model was exhibited at the Columbian Exposition, a world’s fair held in Chicago in 1893.
