Nazi hunter Simon Wiesenthal passed away in his sleep at his home in Vienna, Austria at the age of 96. The LA times has an excellent obituary which concludes as follows:
Wiesenthal spoke often of a Sabbath dinner he had spent at the home of another survivor of Mauthausen, who had become a wealthy jeweler. The man speculated that Wiesenthal could have become a millionaire if he had gone back to architecture instead of hunting Nazis.
“When we come to the other world,” Wiesenthal said he responded, “and meet the millions of Jews who died in the camps, and they ask us, ‘What have you done?’ there will be many answers.
“You will tell them, ‘I became a jeweler.’
“Another will say, ‘I smuggled coffee and American cigarettes.’
“Another will say, ‘I built houses.’
“But I will say, ‘I didn’t forget you.’.”
