Johann Theodor Mosewius

After studying law, he trained as an opera singer (bass) and worked as such at the local theatre, at the time of the management of August von Kotzebue (1814-1816), then he moved to Breslau, where he worked as a singer and actor until his quarrel with the theatre tenant Gottlob Benedict Bierey and the death of his wife.

[2] One year after Mendelssohn's revival of Bach's St Matthew Passion in Berlin,[3] Mosewius rehearsed it in Breslau in 1830 with overwhelming success.

The Institute performed Italian oratorios as well as those by Mendelssohn, Carl Loewe, Louis Spohr, Adolf Bernhard Marx and others.

[5] Mosewius achieved international recognition through his activities and writings, and even during his time at the theatre, he always sought close contact with influential journalists (in Breslau, for example Karl Schall).

From 1810 Mosewius was married with the singer Sophie Wilhelmine, née Müller (1792-1825), who made her debut in Berlin 1805 and afterwards got a job in Königsberg.
