Life and work

After his school days in Cologne and subsequent training to elementary teachers at teacher training college in Brühl, Kaltenbach occurred in 1815 during his first teaching job in the place Hastenrath in Eschweiler, but changed two years later in an upscale elementary school in Aachen. In 1837 he was appointed the Acting Director Johann Joseph Kribben to the former grammar school, which later became junior high school first -order and the present Rhine-Meuse -Gymnasium Aachen, where he taught until his death in 1876.

In addition to his dutiful subjects Kaltenbach prescribed increasingly the natural sciences and an intern in the field of botany at Philipp Wirtgen and in the field of entomology at Arnold Foerster. Soon was Kaltenbach as one of many pioneers of the "applied entomology ".

Alone in his publication "Flora of the Aachen basin " he described more than 800 phanerograms ( seed plants ). However, his major work was declared the manual on "The plant enemies from the class of insects ." Much of his botanical researches and works were recording in the archives of the botanist Carl Friedrich von Ledebour. His botanical abbreviation was " cold. " But also " Kaltenb. ".
