notes: label: Description
content: In 1880, Ludwig Brill published two models of surfaces of rotation of an ellipse that had been designed by A. von Braunmühl (1853-1908), a student and later teacher of mathematics in Munich who would become a well-known historian of mathematics. In this one, the ellipse is rotated about its shorter axis; the resulting surface is known as an oblate spheroid or oblate ellipsoid of revolution. This example was exhibited at the Columbian Exposition held in Chicago in 1893 and later acquired by Wesleyan University.
