Clara Wieck made her official debut on 28 October 1828 at the Gewandhaus in Leipzig, at age nine. The same year, she performed at the Leipzig home of Ernst Carus, director of the mental hospital at Colditz Castle. There, she met another gifted young pianist who had been invited to the musical evening, Robert Schumann, who was nine years older. Schumann admired Clara's playing so much that he asked permission from his mother to stop studying law, which had never interested him much, and take music lessons with Clara's father. While taking lessons, he rented a room in the Wieck household and stayed about a year.
