Possibly the most well-known example of these rescue operations involved individual British families agreeing to “host” children from Germany, Austria, and the Czech Republic through a program known as Kindertransport.  Through this program, organized by Sir Nicholas Winton, an estimated 10,000 refugee children, most of them Jewish, were housed in the United Kingdom during the war.  These children were able to avoid ghettoization and camp experiences; in many cases, they were the only members of their families to survive the Holocaust.
