Johann Gottlob Friedrich Wieck (18 August 1785 – 6 October 1873) was a noted German piano teacher, voice teacher, owner of a piano store, and author of essays and music reviews. He is remembered as the teacher of his daughter, Clara, a child prodigy who was undertaking international concert tours by age eleven and who later married her father's pupil Robert Schumann, in defiance of her father's extreme objections. As Clara Schumann, she became one of the most famous pianists of her time. Another of Wieck's daughters, Marie Wieck, also had a career in music, although not nearly so illustrious as Clara's. Other pupils included Hans von Bülow. Source: Wikipedia (en)
