Dannreuther trained at the Leipzig Conservatory, where he was a pupil of Ignaz Moscheles (1794–1870). In 1863 he moved to London, and subsequently became a naturalised British citizen. He was very prominent in musical circles, founding the London Wagner Society in 1872.
On 11 March 1876 [N.S.], he performed Tchaikovsky's Piano Concerto No. 1 at the Crystal Palace in London, and wrote to the composer suggesting a series of alterations that were subsequently incorporated into the second edition (1879).
