And the money quote:

Until political winds shifted, ex-Nazis were welcomed in Egypt in the years after World War II, helping in particular with military technology. Rdiger Heim said that his father told him he knew other Nazis there, but tried to steer clear of them.

Even so, how Dr. Heim was able to elude his pursuers for so long, while receiving money from Europe, most notably from his late sister, Herta Barth, and corresponding with friends and family in long letters, is unclear.

“The Arab world was an even better, a safer haven than South America,” said Efraim Zuroff, the Israel director of the Simon Wiesenthal Center, who had been searching for Dr. Heim and traveled to Chile last July to raise awareness about the case. Mr. Zuroff expressed surprise when informed of Dr. Heim’s apparent fate, saying the center had been about to raise the reward for information leading to his arrest to $1.3 million from $400,000.
