The German composer and teacher, Christian Theodor Weinlig, was instructed first by his uncle, the organist Christian Eheregott Weiling (1740-1813), and then by Padre Mattei at Bologna.
From 1814 to 1817, Christian Theodor Weinlig was Kantor of the Kreuzschule in Dresden, and in 1823 he succeeded Johann Gottfried Schicht as Kantor of the Thomasschule in Leipzig, and remained there till his death. Among his most well-known pupils were pianist Clara Schumann and composer Richard Wagner.
Christian Theodor Weinlig published a German Magnificat for soli, chorus and orchestra, some singing exercises, and a treatise of some value, Anleitung zur Fuge für den Selbstunterricht (2nd ed. 1852). But it is as a teacher of theory and as the master of Wagner for six months in 1830 that his name will be remembered. Wagner has left his recollections of Weinlig's teaching on record in words which deserve to be pondered by all teachers of theory.
