Geometric Model by A. Harry Wheeler, Union of Three Cubes

<< >>
Massachusetts high school teacher and model maker A. Harry Wheeler built several geometric models that represented the union of intersecting cubes, including this one. The plastic pieces of the model are cut and glued to represent sections of yellow, green, and turquoise cubes.
The model has no maker’s mark, but corresponds to three other models numbered “95.” One of these was made by his student Lois M. Parker in April 1938—it is of balsa wood (see 1979.0102.040). A third version of the model is folded from paper and has only the model number on it (see 1979.0102.043). A fourth version of the model, also folded from paper, has notes in Wheeler’s hand indicating that the model is inscriptible in a cube, a rhombic dodecahedron, a tetrahedron, and an octahedron. These notes are dated 1931 and 1938.
In Wheeler’s handwritten catalog of his models, this model is listed as 95 and also numbered H19, as it was based on a six-sided figure or hexahedron.
