EtymologyEdit

From Latin simplex (simple).

In the mathematical sense, apparently first used (in German) in 1902, Pieter Hendrik Schoute, Mehrdimensionale Geometrie[1], where Schoute first suggests the term Simplicissimum, but then from the next page decides to use simplex "for short".[1] In his pioneering works on algebraic topology, Henri Poincaré had previously introduced the concept, but not the actual term simplex.
