Ernst Gennat's grave

Ernst August Ferdinand Gennat (1 January 1880 – 20 August 1939) was director of the Berlin criminal police. He worked under three political systems in his 30 year career as one of the most gifted and successful criminologists in the German Reich. Among other things, he worked on the cases of Fritz Haarmann and Peter Kürten.

Biography[]

In his childhood, he lived with his parents in a staff housing of the correctional facility in Berlin-Plötzensee. He graduated from high school on 13 September 1898, and entered the faculty of law of the Frederick William University on 18 October 1901. In the years in between one can assume that he served in the military (which he noted as profession on subscription to the university).

On 12 July 1905, he left the university without a degree, shortly before the end of the semester on 15 August. The reason was his career in the police – he had entered the police service in 1904 and passed the examination to criminal police officer on 30 May 1905. Two days later he started as detective assistant and he was promoted to criminal detective on 1 August.

When Gennat entered the criminal police, there was no separate homicide division. It was only on 25 August 1902 that an on-call homicide service was created. That had not even changed when the Berlin police was reorganized on 1 June 1925. Only on the basis of Gennat's efforts was a homicide squad created. This event made possible his promotion to lieutenant inspector (at the age of 45). He had been passed over for promotion beforehand owing to his massive criticism of the conditions in the criminal department.

After creation of the Zentrale Mordinspektion (central homicide inspection) the division achieved enormous success under Gennat's leadership. In 1931, the homicide inspection was solving 108 of 114 crimes making for 94.7 percent (compared to 85 to 95 percent in today's homicide inspection work). Gennat himself worked on solving 298 homicide cases. His department was organized as one standing inspection team with two backup teams. The active team had one senior and one junior homicide inspector accompanied by 4 to 10 criminal police officers, a stenotypist and a dog handler. The backup teams had a senior and junior homicide inspector (bound in a so-called "Mord-Ehe" / homicide marriage) plus 2 to 3 police officers and a stenotypist. The composition of the active team changed every four weeks to ensure that each officer gained enough experience.

Gennat reorganized much of the structure of how to investigate homicide. He developed most of the scheme that is known today as profiling. His work is documented in articles for the public like the 1930 publication "Die Düsseldorfer Sexualverbrechen" about Peter Kürten, where Gennat coined the term "Serienmörder" (serial killer).

During the Third Reich, he was able to continue his work despite keeping a distance from the Nazi Party. Based on his success, he was even promoted to department director in 1934 and vice director of the Berlin police in 1935. He married criminal inspector Elfriede Dinger shortly before his death on 20 August 1939 (he had cancer but his sudden death makes a stroke more likely).

In culture[]

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).[citation needed] Ernst Gennat is a recurring character in several of the Bernie Gunther novels by the late Philip Kerr. German actor Udo Samel plays Gennat in the second and third seasons of the TV show Babylon Berlin.
