Sir Nicholas George Winton MBE (born Wertheim; 19 May 1909 – 1 July 2015) was a British stockbroker and humanitarian who helped to rescue Jewish children who were at risk of being murdered by Nazi Germany during the Holocaust. Born to German-Jewish parents who had immigrated to Britain at the beginning of the 20th century, Winton assisted in the rescue of 669 children, most of them Jewish, from Czechoslovakia on the eve of World War II : On a brief visit to Czechoslovakia, he helped compile a list of children needing rescue and, returning to Britain, he worked to fulfill the legal requirements of bringing the children to Britain and finding homes and sponsors for them. This operation was later known as the Czech Kindertransport (German for 'children's transport').
