Sir Nicholas Winton was 29 when he saved 669 children, most of them Jewish, from the Nazis.
Dubbed the "British Schindler", Sir Nicholas organised eight trains from occupied Czechoslovakia to Britain and helped find foster families for the refugees from 1938. A ninth train carrying 250 children was stopped from coming to Britain when the war began. It's believed those children did not survive.
Today Sir Nicholas is 105 and is being awarded the Czech Republic's highest state honour, the Order of the White Lion, at a ceremony in Prague for his actions.
This video showed what happened when he was reunited with some of the children he saved in an emotional episode of That's Life in 1988.
