"Dülon was born in Oranienburg.Although he went blind due to an eye infection caused by medical malpractice when he was only six weeks old, this did not prevent him from taking music lessons, first from his father, a music-loving tax official, and later from organist Johann Karl Anderson (1774–1815) who taught him piano and figured bass, and the equally blind flutist Joseph Winter who had arrived in town on 16 March 1778.
