"Winton kept quiet about his humanitarian exploits for many years, until his wife Grete found a detailed scrapbook in their attic in 1988. It contained lists of the children, including their parents' names, and the names and addresses of the families that took them in.
"By sending letters to these addresses, 80 of 'Winton's children' were found in Britain. The world found out about his work in 1988 during an episode of the BBC television programme That's Life
! when he was invited as a member of the audience. At one point Winton's scrapbook was shown, and his achievements explained. The host of the programme, Esther Rantzen, asked whether any in the audience owed their lives to Winton, and, if so, to stand – more than two dozen people surrounding Winton rose and applauded."http://en.wikipedia.org/wiki/Nicholas_Winton
