"Whosoever saves a single life, saves an entire universe"
(Mishnah, Sanhedrin 4:5)
Throughout the Holocaust, in a world of moral collapse, there was a small minority who mustered extraordinary courage to uphold human values. In many cases, they never planned to become rescuers, and were unprepared for the moment in which they had to make such a far-reaching decision. They were non-Jews, and many were honored as Righteous Among the Nations.
Then there was Nicholas Winton: an ordinary person with extraordinary humanity. He was a Jew helping Jews, and the world only found out about his efforts over 50 years later, in 1988.
