1820 - 1915
German painter, active in Britain. After studying in Nuremberg, he painted miniature portraits in Munich and Brussels. In 1847 he went to London to study English techniques of watercolour painting and evolved a method that he claimed achieved the 'brilliancy of oil painting, combined with the tender-sweetness of water-colours' . From 1850 he exhibited at the Society of Painters in Water-Colours and was elected a full member in 1853.
