JB Cramer was one of the finest pianists of his day, though his reverence for Mozart made his own music more popular in the drawing room than the concert hall.
In 1772, Wilhelm Cramer, a virtuoso violinist from Stuttgart in the Duchy of Württemberg, settled in London, becoming a leading figure in concert halls and in the Court of King George III. Soon afterwards, his infant son Johann Baptist Cramer (1771-1858) joined him in England.
