Leverkusen (//; German pronunciation: [ˈleːvɐˌkuːzn̩]) is a city in North Rhine-Westphalia, Germany on the eastern bank of the Rhine. To the South, Leverkusen borders the city of Cologne and to the North is the state capital Düsseldorf.
Dating back to the 12th century as Wiesdorf, the Leverkusen area was rural until the late 19th century.
Leverkusen was founded in 1930 by merging Wiesdorf, Schlebusch, Steinbüchel and Rheindorf. The city was posthumously named after the chemist and entrepreneur Carl Leverkus. In 1861, Leverkus set up a factory for the production of artificial ultramarine blue at the Kahlberg in Wiesdorf, and called the emerging settlement "Leverkusen" after his family home in Lennep.
In 1975, Opladen (including Quettingen and Lützenkirchen since 1930), Hitdorf and Bergisch Neukirchen joined Leverkusen. The present city is made up of several villages, originally called Wiesdorf, Opladen, Schlebusch, Manfort, Bürrig, Hitdorf, Quettingen, Lützenkirchen, Steinbüchel, Rheindorf and Bergisch-Neukirchen.
In 1860, Wiesdorf was chosen by the chemist Carl Leverkus for establishing a dye factory. The factory was taken over by the Bayer company in 1891. The company moved its office to Wiesdorf in 1912, turning the town into the centre of German chemical industry. After asset confiscation at the end of WWI it became IG Farben. The IG Farben factories were bombed by the USAAF Eighth Air Force on December 1, 1943, by the RAF on August 22, 1943, and by the RAF during Battle of Berlin (air) on November 19/20 and December 10/11, 1943. The predominance of Bayer could easily classify Leverkusen as a German monogorod.
