Friedrich Konrad Griepenkerl

In 1808, taking Herbart's advice, he went to Hofwil in Switzerland, where he became a teacher of the German language and literature at the newly founded Philipp Emanuel von Fellenberg Institute.

In 1828, he took up an additional teaching position at the Obergymnasium, where he taught German language and literature, mathematics and philosophy.

[2] Griepenkerl founded a singing academy in Braunschweig, which under his direction performed Bach's chorals and his Mass in B minor.

Griepenkerl was in friendly contact with important musicians of his time, such as Carl Friedrich Zelter, Carl Maria von Weber, Gaspare Spontini, Louis Spohr, Giacomo Meyerbeer and Felix Mendelssohn Bartholdy.

Together with Ferdinand August Roitzsch (1805-1889), he published a critical edition of J. S. Bach's piano and organ works in the years from 1837.
