Geometric Model by Agda Carlson, a Student of A. Harry Wheeler, Regular Octahedron

This tan paper cut and folded model consists of twelve equilateral triangles. The pieces can be folded to form a regular octahedron. Circular arcs are indicated in pencil next to many edges

An inscription in pencil on one side reads: Agda Carlson (/) Jan-26-1915. An inscription on the inside (as folded) reads: Original Model.

Agda Carlson (1896-1980) was the Massachusetts-born daughter of Swedish immigrants to the United States. Yearbook records from the Old English High School and New High School of Commerce in Worcester, Massachsetts, for 1915 indicate that she planned to work in a hospital after graduating that year. However, subsequent Census records indicate that she continued to live with her parents and worked in Worcester as a dressmaker (1920) and a lace maker in a factory (1930). She is listed in later Worcester city directories as a “designer.”
