German director of the Berlin criminal police, who worked under three political systems in his 30 year career as one of the most gifted and successful criminologists in Germany. Among other things, he worked on the cases of Fritz Haarmann and Peter Kürten.
Gennat reorganized much of the structure of how to investigate homicide. He developed most of the scheme that we know as profiling today. His work is documented in articles for the public like the 1930 publication "Die Düsseldorfer Sexualverbrechen" about Peter Kürten where he was the first to coin the term "Serienmörder" (serial killer).
Ernst Gennat inspired the fictional character inspector Karl Lohmann who appeared first in Fritz Lang's M (1931) and The Testament of Dr. Mabuse (1932).
Gennat died on 21 August 1939, aged 59, in Berlin.
