The 'Düssel' is a small right
tributary of the River
Rhine in
North Rhine Westphalia. Its source is between
Wülfrath and
Velbert. It runs westward through the
Neanderthal, where the
fossils of the first
Neanderthal man were found in
1856. At
Düsseldorf it joins the Rhine. The name ''Düsseldorf'' comes from the name of the Düssel. (Düssel is the river, and ''Dorf'' means a small town)
