The story of Sir Nicholas Winton is the one that you would imagine could only happen on the silver screen. Sir Nicholas Winton was a British man who went to heroic efforts, potentially putting himself at risk, during World War II. Sir Winton was responsible for ensuring the safety of 669 Jewish children by aiding their escape from countries occupied by Nazis. Finally, the Jewish children were brought to England where he worked to make sure families in his native country would help the kids by taking them into their homes.

Recently, this unbelievable story has again been making the rounds on the Internet, particularly after a rerun of the BBC show called "That's Life", which featured Sir Winton. People around the world were moved at the details of the story, with saying it to be the best story they've ever seen.

Sir Winton kept his entire plan completely secret, even his wife had no idea about his planning until fifty years later. After the war, years passed and many people remained in the dark about Sir Winton's extraordinary achievement. Some fifty years later, his wife Greta was searching in their house and discovered a Winton's notebook which documented the names of all the children. She worked with BBC and they produced a TV episode(插曲) of their program "That's Life" that served as an honor for Sir Winton's work.

In 2003, Sir Winton was knighted by the Queen of England for his work. He also was even nominated for a Nobel Peace Prize. He also had a small planet named after him by Czech astronomers. Sir Winton died peacefully in his sleep at the old age of 106, in 2015. Leaders around the world paid tribute(悼念). Israel's ambassador to the United Kingdom, Daniel Taub, said, "He was a hero of our time, having saved 669 Jewish children from Nazis. His story, as a point of light in a period of darkness, will forever be remembered."
