## History

Hans Dissing and Otto Weitling were key employees at Arne Jacobsen's office and they founded Dissing+Weitling in 1971 upon his death to continue and complete his unfinished projects. These included a city hall in Mainz, Germany, which was also extended by Dissing+Weitling in 2008, a holiday resort on the north German island of Fehmarn, the Danish Embassy in London. In 1972, the firm won competitions for the IBM Centre in Hamburg and the Kunstsammlung Nordrhein-Westfalen in Düsseldorf, establishing the firm's name in its own right. Hans Dissing died in 1998, and Otto Weitling retired from the firm in 2002. Key architects and partners of the past were: Dieter Fremerey, Erik P. Handschuh, Poul Ove Jensen, Pouli H. Møller, Bodil A. Schaltz, Reinhard Schmidt-Petersen, Reinhard Tölke, Teit Weylandt, and Stig Mikkelsen. Current partners are: Steen S. Trojaborg, and Daniel V. Hayden.
