Sir Nicholas Winton: the true story of the British WW2 hero who saved 669 children from the Nazis

Thanks to YouTube and its incomprehensible algorithm, it's likely that you have seen the two-minute clip of the 1988 BBC show This is Your Life, where Nicholas Winton is celebrated by some of the children that he had saved from the Nazis in the lead-up to the Second World War.

The British stockbroker, who died in 2015 aged 106, ended up becoming a key figure in the 1938-1940 Kindertransport task force, which helped to transfer around 10,000 primarily Jewish children out of Nazi Germany, Austria, Czechoslovakia and Poland to Britain following Kristallnacht.
