This large white plaster model has four undulations on both sides of a higher central plateau. Various lines are indicated and numbered.
The model was designed in 1880 by Th. Kuen and Chr. Wolff, working under the supervision of Ludwig Brill at the technical high school in Munich. It shows the surface made by points related to one another via an elliptic integral of the first kind. It represents a graph of the Jacobi amplitude. A sticker on the front reads: 80.
This example of the model was exhibited at the German Educational Exhibit at the Columbian Exposition, a World’s Fair held in Chicago in 1893. It there was purchased by Wesleyan University in Connecticut, and subsequently was donated to the Smithsonian.
