Leopold Dippel

from Wikipedia, the free encyclopedia

Leopold Dippel (born August 4, 1827 in Lauterecken , † March 4, 1914 in Darmstadt ) was a German botanist and author on microscopy .

Life

Dippel was the son of the royal Bavarian head forester Carl Albert Dippel in Lauterecken in northern Palatinate. He attended grammar schools in Kaiserslautern and Zweibrücken and studied from 1845 at the Forest Academy in Aschaffenburg , where he became a member of the Corps Hubertia , which was later moved to Munich . In 1848 he passed the final exam. He later continued his studies in Jena . Here he turned to botany under the direction of Matthias Jacob Schleiden and began his pioneering work in the field of microscopy and his research into the structure of the plant body. In 1854 Dippel passed the state examination for mathematics and natural sciences.

In 1867 Dippel's “The microscope and its application” appeared, a textbook with about 500 pages in which he also examined the quality of microscopes from 14 German and foreign manufacturers.

From July 1869 Dippel worked as a full professor of botany and zoology at the TH Darmstadt in the field of microscopy, botany (since 1871), and cell and tissue theory. This position was associated with the management of the Botanical Garden in Darmstadt from the beginning . This first existed in the Schlossgraben since 1814, but after several moves within Darmstadt it was only moved to its current location in 1874 on the site of the former axis mill in the east of Darmstadt. Dippel was the organizer of this move. The approximately 5 hectare site with a level difference of 12 m, which also comprised wet and dry parts, was also suitable to create a spacious arboretum. Dippel's interest was particularly in dendrology (tree science). The well-known arboretum (Latin arbor = the tree, tree collection) goes back to him. There he brought together a collection of foreign trees that is still significant today, a large part of which Carl Albert Purpus collected in North America and Mexico and sent to Germany. After the death of Karl Koch (botanist) , Leopold Dippel took over his idea and demanded a public national arboretum for the German Reich, which was not realized. At the end of the summer semester of 1896, he retired.

Dippel was dean of the chemical-technical school from 1882–87 and rector of the TH Darmstadt from 1870–71. He was married to Sophie Fried since 1851.
