Lisalotte Milchsack DCMG CBE (née Duden; 27 May 1905 – 7 August 1992[1]) was a German promoter of post-war German-British relations.

She founded an association which created an annual conference of British and German decision makers.

Her education in Frankfurt, Geneva and Amsterdam University instilled in her an awareness of international affairs.

Visiting Britain before the war, she pleaded with Britons to resist Hitler, only to be ignored and labeled a traitor.

The Königswinter Conference was praised by Chancellor Helmut Schmidt as a "a kind of college of higher education in politics" and Prime Minister Sir Alec Douglas-Home said that the conference was a contributor to the trust that existed between Britain and Germany during the last quarter of the twentieth century.

[7] The politician and journalist Bill Deedes called her "one of the architects of post-war Europe"[5] whilst The Independent said she was the "Queen of Anglo-German relations".
