Michael Haydn taught him as a teenager. Vogler also taught him, Meyerbeer being a fellow-student who became a lasting friend. He learned lithography from its inventor Senefelder, and ran a printing business with his father before returning to composition. He suggested that Spohr take on a post in Kassel that he himself had turned down. Mozart’s wife Constanze was his cousin. Mendelssohn, who took him for a role-model, would recognise him in the street and run over to greet him.
