Hermann Grassmann’s 200th Birthday: 15 April 2009

Hermann Günther Grassmann (April 15, 1809, Stettin (Szczecin) – September 26, 1877, Stettin)

was a German polymath, renowned in his day as a linguist and now admired as a mathematician. He was also a physicist, neohumanist, general scholar, and publisher. His mathematical work was not recognized in his lifetime.
