1861–1942
A German naturalist, teacher, and popular science writer, he moved between botany, philosophy, and public debate. He is especially remembered for founding the Keplerbund and for writing forcefully about science and worldview in early 20th-century Germany.

by Eberhard Dennert
Born in 1861 in Pützerlin near Stargard and later dying in Bad Godesberg in 1942, Eberhard Dennert was a German naturalist, botanist, philosopher, and teacher. Reference works describe him as a popular writer on nature and culture as well as an Oberlehrer, showing how closely his scientific interests were tied to education and public explanation.
His work ranged from botany to broader questions about how science should be understood by the public. He also became known as the founder and leader of the Keplerbund, an organization created in 1907 that brought scientific, philosophical, and religious questions into open discussion.
Dennert wrote for readers beyond the academy, which helps explain why his name appears both in scientific bibliographies and in broader biographical dictionaries. Today he is mainly remembered as a figure who stood at the crossroads of natural history, teaching, and the cultural arguments around Darwinism in Germany.
