Nicholas Winton kept a secret, even from his wife Grete, for nearly 50 years. She only learned about it from a scrapbook she found in the attic. The scrapbook detailed the names and photographs of children Nicholas saved from certain death in 1939 before war broke out in Eastern Europe. He arranged safe passage to Britain for over 650 children who otherwise would have been sent to Nazi death camps.
In 1988, Grete discovered her husband's secret, which he never told anyone in half a century. The scrapbook also contained letters from some of the children's parents. The BBC that year aired a surprise reunion between Nicholas and about two dozen of the now-grown benefactors of his life-saving work. Imagine his surprise first to find that one of them was seated next to him, and then to realize he was surrounded by more! It was quite an emotional reunion!
