A 2011 police report stated most of the women working in the street come from Romania, Bulgaria and Poland.

When the Ruhr uprising broke out in defiance of the Kapp Putsch in March 1920, the Ruhr Red Army, whose goal was the establishment of a Dictatorship of the proletariat, put into service the so-called "Red Cross sisters" as medical personnel, who consisted exclusively of prostitutes who were recruited "especially from Oberhausen".

[3] Some of them, the Karbol-Mäuschen (carbolic mice), took part in the looting of Schloss Sythen on March 21, 1920, which was then in the possession of the Count Otto von Westerholt and Gysenberg (1875-1920).

[6][7] The part of Eintrachtstrasse affected by prostitution was renamed Flaßhofstrasse on April 1, 1921 by a decree from the President of the Government of Düsseldorf, Walther Grützner .

He had, with his brother-in-law Jobst Waldthausen and Wilhelm Lueg, drilled exploratory holes on the Lipper Heide and discovered coal in 1845, the Concordia colliery being set-up on the strength of these findings.

[11][12] The president of the Oberhausen Hells Angels, previously head of an earlier chapter of the Bandidos, was the tenant of eight of the 16 houses on Flaßhofstrasse.
