Our history is full of silent heroes: people who did something to change the world, without great fanfare. Nicholas Winton's story only came to light in 1988, when his wife found an old scrapbook of his in the attic and pressed him about it. (Not that he had been idle in the years before that; he had been knighted five years earlier for his work for refugees around the world)
The world lost one of its great men today. But thanks to him, it has nearly a thousand more.
