notes: label: Description
content: In 1877, L. Brill published a plaster model designed by Walther von Dyck (1856-1934), a student of Alexander Brill and Felix Klein at the technical high school in Munich. Dyck would go on make distinguished contributions to combinatorial group theory, to educational administration, and to the history of astronomy.
label: Description
content: This white plaster model shows a surface of revolution of constant negative curvature of the hyperboloid type. It has a round base that expands of a larger round rim and a parenthesis-shaped figure rotated to give the surface of revolution. The top rim contracts again to a round, flat top. Various geodesic lines and circles are indicated.
label: Description
content: A paper tag on the model reads: 133. Another tag reads: Rotationsfl. const. negat. Krümmg. [/] Verl. v. L. Brill. 2. Ser. Nr. X.
label: Description
content: This example of the model was exhibited at the Columbian Exposition, in Chicago in 1893.
