Geometric Model, L. Brill No. 203. Ser. 17 No. 1, Minimal Surface


This white plaster model of a minimal surface is supported by three metal rods above a black wooden stand. A grid of parabolas, as well as a single red line, are indicated. There are no labels.

The model was designed by Hjalmar Tallqvist (1870-1958), a student at the University of Helsinki, under the direction of E. R. Neovius.

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