Son of Louis Schlosser. Was born at Darmstadt, and was educated by his father. He became a gifted pianist, made his debut at Frankfort, and gave recitals in France and Germany. In 1854 he removed to London, where he became a noted teacher, being connected with the Royal Academy of Music as an instructor. Schlosser's " Schumann Evenings " in London did much to make the works of that gifted composer known to the people of England. He wrote a quartet for piano and strings; an idyll; trio; fantaisiestück; a suite in D minor; and set of twenty-four studies for the piano; songs; an Ave Maria; and other vocal pieces.
