Description
The design of this plaster model follows one built Edward Kummer (1810-1893), a mathematics professor in Berlin. Examples were first published by Brill in 1883.
In its complete form, the model has four congruent parts which are arranged with tetrahedral symmetry. This example has only three of those parts and they are presently disjoint. The three pieces present each have the dimensions given. Identical curves are drawn on them. A paper tag reads: Fl. 4. Ord. mit 4 Doppelebenen. [/] Verl. v. L. Brill. 9. Ser. Nr. 6.
This example was exhibited at the Columbian Exposition, a world’s fair held in Chicago in 1893.
