I moved to the Afrikanisches Viertel, in Wedding, about a month after I arrived in Berlin. Most of the streets are named for places in Africa – Togostraße, Windhukerstraße – but Nachtigalplatz commemorates Gustav Nachtigal, Bismarck’s Reichskommissar for West Africa, and Lüderitzstraße is named for the founder of German South West Africa. Only one of these colonial names has been changed – sort of. In 1986, the city announced that Petersallee now referred to Hans Peters, a co-founder of the CDU and a member of the Kreisau Circle of wartime resisters. Small panels were attached to the street signs giving his name and dates. But the street was originally named for Carl Peters, an imperial high commissioner of northern Tanganyika in the 1890s and a notoriously brutal, violent racist, condemned even in his own time.
