vielecke u. vielflache (11. 368)

This 1900 study of polyhedra by geometer Johannes Max Brückner, who taught at a Gymnasium (a secondary, preparatory school) in Bautzen after earning a degree in mathematics and physics from the Universities of Leipzig and Heidelberg and earned his teaching credentials for constructing many models of stellated shapes, compounds of the Platonic solids projected outward until the result in a new uniform and congruent three dimensional figure (see also), is not only noted for its aesthetic and inspirational value (M C Escher’s work was largely informed by exposure to this publication) but is considered among the foundational proofs of the field, documenting all the then known possibilities. In 1930, Brückner’s collection of models were donated to the institution in Baden-Württemberg, which in turn awarded him with another honorary degree. More at Present /&/ Correct at the link up top.
