Leica and the Nazis

In an article entitled Leica and the Nazis Andrew Nemeth notes:

Some German corporations didn't exactly distinguish themselves during WW2, with many fostering an unnaturally close association with the Nazi regime, as well as ruthlessly exploiting their slave labourers & employees.

I'm sure many of you have wondered: "Where were Leica in all this? How deeply did they get involved? Were they Good Blokes, or Creeps?"

Thanks to the efforts of Rabbi Frank Dabba Smith, George Gilbert and Norman C. Lipton, the good news is that in this particular case, E.Leitz did do the right thing. Not only did they treat their workforce reasonably well, but they also helped many Jews (and others) escape the depravity of the Thousand Years Reich - often at great personal risk.
