Top litigator Randol Schoenberg has accomplished what few thought possible. After a seven-year struggle with the Austrian government, he recovered Gustav Klimt’s famous “Golden Lady” painting and other Klimt artworks stolen by the Nazis from the Altmann family home in Austria in 1938. Schoenberg’s experiences are the subject of the movie "Woman in Gold," starring Ryan Reynolds and Helen Mirren which he explored in this 2020 program.
