Wolfgang Franke (botanist)

from Wikipedia, the free encyclopedia

Wolfgang Franke (born March 19, 1921 in Leipzig ; † November 10, 2001 in Bonn ) was a German botanist .

Life

Franke began studying botany in Leipzig in September 1940 , but had to interrupt his studies in February 1941 and was drafted into the Wehrmacht . After his release from captivity, he studied biology in Heidelberg from April 1947 . After the state examination in November 1951 in botany, zoology, chemistry and physics, he received his doctorate in botany in February 1952 under August Seybold . From summer 1952 to spring 1954 he was a research assistant at the University of Heidelberg. From April 1954 he worked as a scientific assistant at the Institute for Agricultural Botany of the Agricultural Faculty of the University of Bonn . There he completed his habilitation in January 1957.

On April 1, 1968 Franke took over the management of the institute, and from 1968 to 1986 he was the head of the Institute for Agricultural Botany and Director of the Agricultural Botanical Garden at the University of Bonn. As a major change, he designed the garden into today's useful plant garden, provided that its areas were not needed for experiments.

In his teaching, he represented agricultural botany and crop science with a focus on crops from the tropics and subtropics .

His scientific work focuses on the field of plant anatomy (investigation of ectodesms (= ectocythodes)), fruit morphology (structure and development of the fruits of crops ), herbal ingredients (in particular vitamin C content of crops, protein content of wild vegetables and wild herbs ).

As an essential result of his interests and research, he wrote the scientific textbook "Nutzpflanzenkunde. - Useful plants of the temperate latitudes, subtropics and tropics" (see writings).

Private

Until his death Franke was married to the biologist Elsa Franke (née Wolfgang), whom he had met during his studies. They have three children together. With her expertise in his field of activity, his wife supported him throughout his career in his scientific activities and his publications.
