Wow, I can't believe I've never heard about this man before:

<< Nicholas Winton, a Briton who said nothing for a half-century about his role in organizing the escape of 669 mostly Jewish children from Czechoslovakia on the eve of World War II, a righteous deed like those of Oskar Schindler and Raoul Wallenberg, died on Wednesday in Maidenhead, England. He was 106. ...

Nearly all the saved children were orphans by war’s end, their parents killed at Auschwitz, Bergen-Belsen or Theresienstadt. After the war, many remained in Britain, but others returned to Czechoslovakia or emigrated to Israel, Australia or the United States. The survivors, many now in their 70s and 80s, still call themselves “Winton’s Children." ...

On Sept. 1, 2009, 70 years after the onset of the war halted the rescue operations, a special train with a locomotive and carriages from the 1930s left Prague to re-create the perilous 1939 journeys. On board were some of the original Winton’s Children and many of their descendants, whose numbers now exceed 6,000.

They were met at Liverpool Street Station by Mr. Winton, who had just turned 100. >>

And then he didn't tell anyone what he had done for 50 years. There's a documentary about him I want to watch, and a number of profiles of him online:
