Sir Nicholas Winton

It is often said that our greatest heroes are those who simply go about their heroism without advertisement or herald.    Sir Nicholas Winton kept his heroism a secret for nearly half of a century. 

It is often discussed, about the effects of one action rippling through time and history.   
It's not only the people he directly saved (many of whom stood up in acknowledgement at the end of this video) that owe their lives to him.   It's their families, and their children (and in turn, their children), that Sir Nicholas Winton made possible, that owe him a debt.  

We all do.
