Johann Heinrich Kaltenbach (born October 30, 1807 in Cologne , † May 20, 1876 in Aachen ) was a German botanist and entomologist . His botanical author's abbreviation is “ Kaltenb. "

Live and act

After his school days in Cologne and subsequent training as an elementary teacher at the teachers' seminar in Brühl , Kaltenbach began his first teaching position in Hastenrath near Eschweiler in 1815 , but only two years later switched to an upscale elementary school in Aachen. In 1837 he accepted a call from the incumbent director Johann Joseph Kribben to what was then the higher middle school, the later secondary school 1st order and today's Couven-Gymnasium , where he taught until his death in 1876.

In addition to his compulsory subjects, Kaltenbach increasingly devoted himself to the natural sciences and sat in on the field of botany with Philipp Wirtgen and in the field of entomology with Arnold Foerster . Soon Kaltenbach was considered one of the many pioneers of "applied entomology". As a result, he first joined the "Society for Useful Sciences" in Aachen and also the "Entomological Association of Stettin " and the Zoological-Botanical Society of Vienna and, from October 1834, the Botanical Association on the Middle and Lower Rhine and the subsequent natural history Association of the Prussian Rhineland and Westphalia .

He wrote down his research results in several important publications of his time, whereby the knowledge about native species played a special role for him. In his publication Flora des Aachener Basin alone , he described more than 800 phanerogams ( seed plants ). His main declared work, however, was the manual on the plant enemies from the class of insects . A large part of his botanical research and works were recorded in the archive of the botanist Carl Friedrich von Ledebour . Its botanical abbreviation was: "Kalt." But also "Kaltenb."

As part of his school service, it was a particular concern of Kaltenbach to incorporate his interdisciplinary scientific research into the teaching content of geography and local history . So he first set up a guide for natural teaching in geography and wrote his much-acclaimed main work, the Aachen region . Guide for teachers, travelers and friends of local history , in which he not only went into the history of origin, the characteristics as well as the population and their most important cities, towns, castles and palaces, but also intensively with the climate, soil conditions, flora and fauna of this region busy.

For his life's work, Johann Heinrich Kaltenbach was awarded the Order of the Red Eagle, First Class, one year before his death and as part of his 50th anniversary with the company .
