“ Twin brother of (the landscape-painter) Gustav Paul C. … Training to a xylographer with Messrs. Allgaier & Siegle in Stuttgart and 1859/60 with Brend’amour in Dusseldorf. In 1861 he founds together with his colleague Ruff in Stuttgart an own xylographic institute, whose exclusive owner he becomes in 1869 and

which develops into one of the most esteemed one in Germany

(with temporarily up to 30 journeymen). C. is decisively involved in

that in this time the wood engraving

becomes an important practice of reproduction.

Art journeys together with the twin brother result not only in own wood engravings and small paintings, but

led to own painterly treatment of the engraving,

by whose technical brilliance

C. soon becomes one of the best of his profession.

For the general importance of the wood engraving see also Osteneck, (To the Xylographic Description in the 19^th Century), in Luneburg Contributions to the Research of the View, 1983, pp. 120 ff. + Hanebutt-Benz, (Studies to the German Wood Engraving in the 19^th Century), Frankfort on the Main 1984.
