In the aftermath of World War II, Thonet lost all of its production facilities in the Eastern Bloc states through expropriation, and the sales office at Viennas Stephansplatz had been destroyed during the war. From 1945 to 1953, Georg Thonet, the great grandson of company founder, Michael Thonet, rebuilt the completely destroyed facilities in Frankenberg, Hesse, in the north of Hesse, where Thonet GmbH's head office and production facilities remain until today. Economic success returned quickly and the company sought the cooperation of outstanding designers. The list of designers who have worked with Thonet over the past 60 years is long and filled with top caliber names: Egon Eiermann, Verner Panton, Eddie Harlis, Hanno von Gustedt, Rudolf Glatzel, Pierre Paulin, Gerd Lange, Hartmut Lohmeyer, Ulrich Böhme and Wulf Schneider, Alfredo Häberli, Christophe Marchand, Lord Norman Foster, Delphin Design, Glen Oliver Löw, James Irvine, Piero Lissoni, Stefan Diez, Lievore Altherr Molina, Lepper Schmidt Sommerlade, Hadi Teherani, Läufer + Keichel. Moreover, the company's own design team regularly adds new designs to Thonet's portfolio.
