Baker, Richard P.
Description
This painted plaster model is one of several hundred designed and made by Richard P. Baker, who taught mathematics at the University of Iowa in the early twentieth century. A typed paper label attached to one side reads: No. 430* (/) Spherical repr's (/) xyz + x - y = 0. The surface has two clear local minimums and two local maximums.
The model apparently is not listed in Baker's 1931 catalog, but models with similar numbers are grouped in the category "analytic geometry."
