(Born: Schwerin, Germany, 12 April 1858; Died: Aachen, Germany, 17 November 1937) German mineralogist.

In 1881 Klockmann graduated from the University of Rostock with a doctorate in mineralogy. In 1887 he became a professor of mineralogy and geology at the Mining Academin in Clausthal, but took a position in 1899 as professor of mineralogy and petrology at the Technical Highschool in Aachen where he spent the remainder of his career, becoming emeritus professor in 1923.

Very scarce. This is the first appearance of a popular series of textbooks of mineralogy that would continue to be revised and expanded through other editors and authors to the present day, becoming known simply as Klockmann's Lehrbuch. The basic themes of the science typical of all great textbooks are covered, including crystallography, the physics of minerals and chemical properties. The second part is a descriptive mineralogy. The work became widely used in the German education system.
