Sharansky and three low-level Western spies (Czech citizen Jaroslav Javorský and West German citizens Wolf-Georg Frohn and Dietrich Nistroy) were exchanged for Czech spies Karl Koecher and Hana Koecher held in the United States, Soviet spy Yevgeni Zemlyakov, Polish spy Marian Zacharski and East German spy Detlef Scharfenorth (the latter three held in West Germany). The exchange took place on the Glienicke Bridge between East and West Berlin, which had been used before for this purpose. Sharansky immediately immigrated to Israel, adopting the Hebrew name "Natan" and eventually simplifying his surname to Sharansky.
Bernard Natan from prison, the French government handed him over to the occupying German authorities. Natan was sent to the Auschwitz concentration camp on September 25, 1942, where it is believed he died in 1943. Bernard Natan's importance to the French film industry should not be underestimated. He pioneered the vertical integration of the French film industry, and adopted the "American model" of film-making and distribution. This model provides the underpinning of the French film industry even in the 21st century. Indeed, Pathé survived into the 1980s almost solely on revenues generated by the companies purchased and integration instituted by Bernard Natan.
