Josef Mengele, the notorious Nazi doctor who made selections on the ramp at Auschwitz and experimented on twins and dwarves, escaped to Argentina at the end of World War II and was never captured. It now turns out that at one time Mossad agents knew of Mengele's whereabouts but chose not to capture him at that time. When Mossad agents entered Argentina in 1960 to capture Adolf Eichmann, they also found Mengele. Although they had a chance to capture Mengele in his apartment, they worried that trying to covertly capture two fugitives would endanger both operations. After Eichmann had been whisked away to Israel for trial, Mossad went back for Mengele but he had already fled. Mengele died in 1979 in Brazil while swimming in the ocean.

During World War II, the large estate of Bletchley Park in England was turned into a secret British code-breaking facility. The mansion and surrounding buildings were transformed into offices and housing for the cryptanalysts who deciphered German codes from such machines as the Enigma and Lorenz. Although the grounds and mansion at Bletchley Park were turned into a museum, many of the buildings are falling into disrepair. Privately run by a trust rather than by the government, the Bletchley Park Trust is hoping to raise £10 million ($18 million) to restore the buildings and to modernize the museum.
