Heinrich Prell

[2] After receiving his doctorate in Marburg in 1913, with a dissertation titled Das Chitinskelett von Eosentomon, ein Beitrag zur Morphologie des Insektenkörpers ("The chitinous skeleton of Eosentomon, a contribution to the morphology of the insect body"),[1] he worked as an assistant to Karl Escherich at the Royal Saxon Academy of Forestry in Tharandt.

In the summer of 1914, Prell presented his thesis "On the relationships between primary and secondary sexual characters in butterflies" and became a private lecturer in zoology and comparative anatomy.

After serving as a junior field doctor in the Wehrmacht's bacteriological laboratories during World War I, he was appointed associate professor at the University of Tübingen in 1919.

After the end of World War II, in addition to his duties in Tharandt, Prell took over the chair for general zoology in the mathematics and natural sciences faculty in Dresden until it was replaced in 1954.

He dealt with the morphology of protura and butterflies, with viral infections in forest pests, the silk moth (Bombyx mori) and the honey bee (Apis mellifera), with bee losses due to industrial exhaust gases and with gradations of the gray larch moth (Zeiraphera griseana) and the Nun (Lymantria monacha).
