In 1939, on the eve of World War II, a young British stockbroker by the name of Nicholas Winton did something truly incredible.

He risked his life to successfully save 669 mostly Jewish children from Czechoslovakia during The Holocaust by ensuring their safe passage to Britain.

Like a true hero, he never spoke of it again until fifty years later when his wife found a scrapbook in the attic of their home that contained the names, pictures and documents of the children that he saved.

Sir Nicholas, who was also knighted by Queen Elizabeth II in 2003 and who received the Czech Order of the White Lion in 2014, died on July 1, 2015, aged 106. Dubbed the “British Schindler” by the British press, he appeared on a UK television programme called That’s Life! in 1988.

He was invited as a member of the audience, totally unaware that the people sitting around him were only alive because of his bravery and selflessness. Watch the video below to see the moment he finally realized. Get your handkerchief near you.
