He was also a very successful lecturer and a forceful writer, his contributions to reviews and newspapers having been since collected in book form. He also published among others: "Musikalisches und Persönliches" (1870), "Wie hören wir Musik?" (How do we hear listen to music?, 1880); "Goethes musikalisches Leben" (Goethe's musical life, 1880); and "Erinnerungsblätter" (Reminiscences, 1884). He published an account of his friendship with Mendelssohn in 1874. Part of his vast correspondence with other musicians and artists of his period, which is in itself an important historical archive, has been published in seven volumes.
