Johann Christian August Heyse

Johann Christian August Heyse (21 April 1764 in Nordhausen – 27 June 1829 in Magdeburg) was a German grammarian and lexicographer. He was the father of philologist Karl Wilhelm Ludwig Heyse (1797–1855), who edited and revised several of the elder Heyse's works.^[1]

From 1783 to 1786 he received his education at the University of Göttingen. He later was a schoolteacher in Oldenburg (from 1792), an academic rector in Nordhausen (from 1807) and a school director in Magdeburg (from 1819 until his death).^[2]

He is chiefly known for his work in the field of German school grammar. He wrote:
