by Max Löhlein
Max Hermann Friedrich Löhlein (June 3, 1877 – December 27, 1921) was a German doctor, pathologist, and professor. He studied medicine at the universities of Bonn, Würzburg, and Gießen, later worked in Leipzig and Halle, and spent time at the Institut Pasteur in Paris.
After qualifying in general pathology and pathological anatomy in 1906, he taught in Leipzig and later worked at the municipal hospital in Berlin-Charlottenburg. He traveled abroad as well, including a stay in Cameroon from 1910 to 1911, and published Beiträge zur Pathologie der Eingeborenen von Kamerun in 1912. In 1918 he became full professor of general pathology and pathological anatomy and director of the Pathological-Anatomical Institute at the University of Marburg; from 1920 to 1921 he also served as dean of the medical faculty.
Löhlein is also remembered as the author of Die krankheiterregenden Bakterien, a work written to explain bacterial infectious diseases in an accessible way for general readers. He died in Marburg in 1921 as the result of a severe infection contracted in the course of his work.
