Ludwig Schläfli [SEP] date of death
Ludwig Schläfli
Ludwig Schläfli (15 January 1814 – 20 March 1895) was a Swiss mathematician, specialising in geometry and complex analysis (at the time called function theory) who was one of the key figures in developing the notion of higher-dimensional spaces. The concept of multidimensionality has come to play a pivotal role in physics, and is a common element in science fiction.

1853 Ludwig Schläfli had discovered many polytopes in higher dimensions, although his work was not published until after his death. Higher dimensions were soon put on firm footing by Bernhard Riemann's 1854 thesis, "Über die Hypothesen welche der Geometrie zu Grunde liegen", in which he considered a "point" to be any sequence of coordinates ("x", ..., "x"). The possibility of geometry in higher dimensions, including four dimensions in particular, was thus established.
