Model for Desargues' Theorem with Triangles in Different Planes, by Richard P. Baker, Baker #49a


This metal model was constructed by Richard P. Baker. A mathematics professor at the University of Iowa, Baker believed that models were essential instruction in many parts of mathematics and physics. Over one hundred of his models are in the NMAH collections.

The painted wire structure is a model for Desargues' Theorem. A paper tag reads: No. 49a Desagues' Theorem by (/) projection (/) Triangles in different (/) planes. This version of the model is not listed in Baker's 1905 catalog, but is included in the 1931 catalog. The model sold for $2.50.
