His best-known work is the 18-volume Lexicon of Saxony, which was completed after his death by Albert Schiffner [de].
He wrote Junker Kurt von Krötenstein's verliebte Heldenfahrt (Lord Kurt von Krötenstein's Hero's Journey of Love) under the pen name of Legaillard.
[1][better source needed] Schumann was born on 2 March 1773, as the oldest of 6 siblings, to the couple Johann Friedrich Schumann and Christiane Magdalena Bohme.
The father worked as a pastor in Endschutz, and had little money around; due to this August Schumann was unable to achieve higher education.
[2] August married Johanna Christiana Schnabel (1767–1836) and was the father of five children: Emilie (born in 1796, who committed suicide in 1826),[3] Eduard (1799–1839), Carl (1801–1849), Julius (1804–1833) and the composer Robert Schumann (1810–1856).
