Weimar Germany (1918–1919) Arthur Hermann Florstedt (18 February 1895 – 5 April 1945) was a German SS official who served as the third commandant of Majdanek concentration camp from November 1942 to October 1943.

Florstedt rose through the ranks of the SS to hold high-ranking positions at various Nazi concentration camps from 1939, including Buchenwald where he developed a reputation for brutality against prisoners.

[1] Arthur Hermann Florstedt was born on 18 February 1895 in Bitsch, Bezirk Lothringen (present-day Bitche, France) the son of an Imperial German Army sergeant.

Florstedt was discharged from the army in January 1919 and moved to Weimar, where he married Charlotte Wille in May 1922, and was active in the right-wing paramilitary Stahlhelm military association from 1920 to 1924.

After the Nazis came to power in early 1933, Florstedt was appointed mayor of Eisleben in April and took part in the political repression in the town, allegedly participating in the torture of KPD members.

In personnel report from September 1935 signed by Hans-Adolf Prützmann, he received a glowing review from his commanders, though his behaviour would lead to a series of reprimands.

On 2 December 1935, Florstedt received a fine of 300 RM for disturbing the peace and property damage after he had caused a drunken riot at a Bruchsal police station the day before.

[3] Florstedt was charged with corruption (wholesale stealing from the state); he had access to valuables stolen from those murdered at the Belzec, Sobibor and Treblinka camps.

On 24 April 1962 the Thüringer Tageblatt, a newspaper of the Christian Democratic Union in East Germany, reported that Florstedt worked for the Kriminalpolizei in Mainz.

The Central Office of the State Justice Administrations for the Investigation of National Socialist Crimes considered Florstedt's death to be unproven according to a memo dated 6 October 1975.
