Q:Found the following article online, use it to answer the question: What is the full name of the person that is married to Rachel?  Joseph Krauzenberg is a very wealthy Hungarian Jewish industrial tycoon whose fortune is mirrored in the great palaces he owns. However, by 1944 his important businesses are needed by the Nazis and Hitler's 'Final Solution' is sweeping through Europe. The Nazis are greedy to accumulate wealth as easily as possible, and under the terms of the Third Reich's "Europa Plan", Krauzenberg arranges with Nazi leaders to exchange his fortune, his business holdings (textile plants, steel mills, ownership of several banks) and a collection of rare art for safe passage to Switzerland for himself, his wife Rachel, and their family. As the night of transaction approaches, Krauzenberg visits his large family being held by the Gestapo, and reassures them that all will be safe. Such is Krauzenberg's wealth and power that when he agrees to sign over his property, it is two of the most powerful men in the Nazi regime who announce they will be coming to his house to handle the paperwork – Adolf Eichmann and Heinrich Himmler. However, as the Nazi leaders are ushered into Krauzenberg's home, they are struck by something unusual – his two most trusted servants, Hans Vassmann and his wife Ingrid are a married Aryan couple who, despite the law, are still working for Jews. As it happens, Eichmann and Himmler's suspicions are well-founded – despite appearing to be the perfect Aryan couple, Hans and Ingrid are actually Jews working deep undercover with the underground Resistance. Young, married, in love and expecting their first child, they work as valet and maid for the elderly Jewish couple. They have everything to look forward to or so they would have believed.
A:
Joseph Krauzenberg
