Dresdner Bank
Dresdner Bank expanded its network with acquisition and opening new offices not only in Europe but also in the United States, Singapore, Canada, Australia, Japan, Hong Kong, and China. Dresdner Bank was the first to open its own office in former eastern Germany in Dresden on 2 January 1990. After the acquisition of Kleinwort Benson in 1995 to form its investment-banking arm Dresdner Kleinwort, Dresdner Bank took over the American investment bank Wasserstein Perella Group Inc., New York in 2000. This investment banking unit was then renamed Dresdner Kleinwort Wasserstein.
