Berlin's pedestrian crossing symbol, the Ampelmännchen, was developed in 1961 by traffic psychologist Karl Peglau for the GDR Ministry for Transport to stem the increasing risk of road traffic accidents. At that time, the Ampelmännchen was the first of its kind in the world.
Since 1996, visitors have been able to buy both types of Ampelmännchen, red and green. The Berlin design company Ampelmann® has developed a range of extremely functional lifestyle products: from calendars, keyrings, earrings and bags to T-shirts and Ampelmännchen lamps. Naturally, there is now also a female version, the Ampelfrau. There are several Ampelmann® stores in Berlin, for example at Hauptbahnhof (central station), at Kurfürstendamm, at the Hackesche Höfe, at Gendarmenmarkt, or close to the Berliner Dom.
