Together with Mozart and of course, Jo Haydn, I was one of the founding members of the Viennese Classic. Many people state that I was strongly influenced by both Jo and Wolfgang. But while Jo was traveling to England twice, he hasn’t had a lot of time teaching me.
Therefore I only studied under him from 1792 to 1794. In a bout of juvenile arrogance, I once claimed that I never learned anything from him but rumor has it that i was just saying it as an insult. Jo once criticized my Piano Trio Op. 1 No. 3. The nerve!
Afterwards I secretly studied under other teachers, like Schen, Albrechtsberger, and Antonio Salieri.
Sadly I cannot help you with your search for the culprit – due to my deafness, I had to lead conversation books, you see. But wait! Maybe some letters of the name of the thief are just mixed up!
