In 1938, there was a rescue effort to save Jewish children from Nazi Germany. The informal name of the program was Kindertransport. It was pushed for by a group of Jewish and Quaker leaders and adopted by the British government.
Children selected for rescue would have to leave their families behind. Once in the UK, they would be housed in foster homes or in a camp. Which meant that for many of the kids that came, they would never see their parents again.
The program would last for two years, and save close to 10,000 children. This photograph is of two of them.
