Daniels, Roland


Born Jan. 20, 1819, in the village of Engelsdorf, near Cologne; died there Aug. 29, 1855. German revolutionary. Member of the Communist League. Friend and colleague of Marx and Engels. A physician by profession.

Daniels met Marx for the first time in 1844 in Paris and under his influence became a materialist and communist. In 1850 and 1851 he played a leading role in the activity of the Central Committee of the Communist League in Cologne. He was arrested in June 1851, but at the Cologne trial of communists in November 1852 he was acquitted for lack of evidence.

Daniels was the author of a large unpublished work, Microcosmos: A Sketch of Physiological Anthropology (1850), which was the first attempt to apply Marx’ philosophical views in the natural sciences.
