In November 1938, following organized attacks on Jewish homes across Germany known as Kristallnacht ("night of broken glass"), British refugee organisations lobbied the British government to permit Jewish children under the age of 17 to be brought temporarily to Britain. Each child's financial upkeep and education was paid for by private individuals. Parents were not allowed to accompany their children.
Between December 1938 and September 1939, when World War 2 began, the kindertransport trains brought 10,000 children to Britain. Many never saw their families again.
