Günther Enderlein

Günther Enderlein was a German zoologist, entomologist, microbiologist, researcher, physician for 60 years, and later a manufacturer of pharmaceutical products. Enderlein received international renown for his insect research, and in Germany became famous due to his concept of the pleomorphism of microorganisms and his hypotheses about the origins of cancer, based on the work of other scientists. His hypotheses about pleomorphism and cancer have now been disproved by science and have only some historical importance today. Some of his concepts, however, are still popular in alternative medicine. A blood test is named after him: dark field microscopy according to Enderlein.
