The scandal that followed Mesmer's only partial success in curing the blindness of an 18-year-old musician, Maria Theresia Paradis, led him to leave Vienna in 1777. In February 1778 Mesmer moved to Paris, rented an apartment in a part of the city preferred by the wealthy and powerful, and established a medical practice. There he would reunite with Mozart who often visited him. Paris soon divided into those who thought he was a charlatan who had been forced to flee from Vienna and those who thought he had made a great discovery.
