(b Berlin, 20 July 1847; d Berlin, 8 Feb. 1935). German painter (of portraits, figure subjects, and landscapes), etcher, and lithographer, active principally in Berlin. From 1873 to 1878 he lived mainly in Paris, and together with Corinth and Slevogt he came to be considered one of the leading German representatives of Impressionism. In 1899 he became first president of the Berlin Sezession, but he did not keep abreast of developments and a decade later he was regarded as a pillar of the traditionalism against which the German Expressionists were in revolt.
