Eichmann before Jerusalem

Smuggled out of Europe after the collapse of Germany, Eichmann managed to live a peaceful and active exile in Argentina for years before his capture by the Mossad. Though once widely known by nicknames such as 'Manager of the Holocaust', he was able to portray himself, from the defendant's box in Jerusalem in 1960, as an overworked bureaucrat following orders - no more, he said, than 'just a small cog in Adolf Hitler's extermination machine'.

How was this carefully crafted obfuscation possible? How did a principal architect of the Final Solution manage to disappear? How had he occupied himself in hiding?
