Named after Bismarckstraße, which honours Otto von Bismarck.
Once called Mühlenweg (mill road) after the mills along it, the street was named on 11 March 1867 after the Prussian Minister President Otto von Bismarck (1815–1898), later the first Chancellor of the German Empire. Curiously, the station further east now called Deutsche Oper opened in 1906 under the name Bismarckstraße.
