A celebrated German writer, whose versatility displayed itself in numerous tales, sketches, art-criticisms, etc., all bearing the impress of a strong, if wayward, intellect; born at Konigsberg, was trained to the law, and entered the State service; his position at Warsaw was lost to him on the entry of the French troops in 1806, and for some years he supported himself by musical criticism in Leipzig, and as Director of a Dresden Opera Company; in 1816 he was again in government service at Berlin, where he continued till his death; his writings are strongly characteristic of the romanticism of his time, while he himself was a witty, restless leader of Bohemian life (1776-1822).
