Berger is today half-forgotten, best-known for those he taught. He himself was taught by Clementi, whose staunch supporter he remained, and by Field. Runge and he struck up a close friendship when he went to Dresden in order to study with Johann Gottlieb Naumann, who unfortunately had just died. In London, he met up again with Clementi, and also got to know Clementi’s student Cramer. Back in Berlin salon society, he got to know Müller – both of them, and the poet Brentano, were unrequitedly in love with Luise Hensel, Fanny Mendelssohn’s sister-in-law. The Mendelssohns were his best-known students.
