Gymnasial-Professor, who wrote several influential books on physics and mathematics and various notes (Schulprogramme) which influenced his son Hermann. According to a biographical sketch by H. Grassmann himself,

he was slow in school, and his father pointed him to a career as gardener.

However, he finished the Gymnasium with a high grade and went on to Berlin

together with his brother studying theology.

During that time his interest in mathematics arose and he wrote a treatise

on the theory of the tides (Theorie der Ebbe und Flut, Prüfungsarbeit 1840, published by Justus Grassmann) to grade for a mathematics teacher position.

His Geometrische Analyse was submitted to the Fürstliche Jablonowski'schen Gesellschaft, as the only candidate, to reestablish or to newly invent a coordinate-free geometric calculus in the spirit of

Gottfried Wilhelm Leibniz. The award was given on July 1, 1846.

The main mathematical works of Grassmann are found in his two books on the

theory of extensive magnitudes (Die lineale Ausdehnunglehre, ein neuer Zweig der Mathematik, 1844 and Die Ausdehnunglehre: Vollständig und in strenger Form bearbeitet, Berlin 1862, cited and known widely as A1 and A2). Unfortunately these works did not receive the attention they deserved http://www.maths.utas.edu.au/People/dfs/Papers/GrassmannLinAlgpaper/GrassmannLinAlgpaper.html. The A1 was submitted as a Ph. D. thesis, but Ferdinand Möbius felt unable to evaluate the work and forwarded it to Ernst Kummer; who rejected it without having studied it carefully.

Not only was Grassmann a great mathematician, he was doing research in physics (crystallography, electromagnetism, mechanics etc.) and physiology (theory of colours, theory of vocals). His colour theory and the three Grassmann laws are still widely known and taught by practitioners. His book on arithmetics could still be printed having an astonishing modern style.

After the complete failure of reception of his mathematical works, Grassmann turned to linguistics. He wrote books on German grammar, collected folk songs, and started to study Sanskrit. His dictionary to the Ayurveda and the translation of this holy book (still in print in Germany) were well recognized among philologists and he received a honorary doctorate from the University of Tübingen in 1876.
