He studied medicine and other subjects at the
University of Leipzig (1728–35), where one of his instructors was the naturalist
Johann Ernst Hebenstreit (1703–1757). From 1742, he gave lectures in
physiology, botany and
materia medica at the
University of Frankfurt, afterwards relocating to Berlin as a professor of botany at the
Collegium Medico-chirurgicum and director of the local
botanical garden. Beginning in 1770, he gave lectures at the recently established institute of
forestry, where he was instrumental in providing a scientific basis for the field of forestry. In his experiments involving
plant movement, he demonstrated the influence that climatic factors had upon
plant organs. Also, his view on the role that insects play in
pollination of plants was considered to be ahead of its time. The botanical genus
Gleditsia (family
Fabaceae) is named in his honor, as is the botanical journal
Gleditschia. In
Berlin-Schöneberg, a thoroughfare called
Gleditschstraße bears his name. == Selected works ==
