In 1980 the Pedagogigal University Bonn was merged into the University of Bonn, although eventually all the teachers education programs were closed in 2007. In 1983 the new science library was opened. In 1989 Wolfgang Paul was awarded the Nobel Prize in Physics. Three years later Reinhard Selten was awarded the Nobel Prize in Economics. The decision of the German government to move the capital from Bonn to Berlin after the reunification in 1991 resulted in generous compensation for the city of Bonn. The compensation package included three new research institutes affiliated or closely collaborating with the university, thus significantly enhancing the research profile of the University of Bonn.
