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.

The Rotary Club of Maidenhead, of which Mr. Winton was a former president, announced his death on its website. He lived in Maidenhead, west of London.

It was only after Mr. Winton’s wife found a scrapbook in the attic of their home in 1988 — a dusty record of names, pictures and documents detailing a story of redemption from the Holocaust — that he spoke of his all-but-forgotten work in the deliverance of children who, like the parents who gave them up to save their lives, were destined for Nazi concentration camps and extermination.

For all his ensuing honors and accolades in books and films, Mr. Winton was a reluctant hero, often compared to Schindler, the ethnic German who saved 1,200 Jews by employing them in his enamelware and munitions factories in Poland and Czechoslovakia, and to Wallenberg, the Swedish businessman and diplomat who used illegal passports and legation hideaways to save tens of thousands of Jews in Nazi-occupied Hungary.
