As soon as Adolf Hitler was named chancellor of Germany in 1933, Ernst Leitz II began receiving frantic calls from Jewish associates, asking for his help in getting them and their families out of the country.
As Christians, Leitz and his family were immune to Nazi Germany's Nuremberg laws, which restricted the movement of Jews and limited their professional activities.
To help his Jewish workers and colleagues, Leitz quietly established what has become known among historians of the Holocaust as "the Leica Freedom Train," a covert means of allowing Jews to leave Germany in the guise of Leitz employees being assigned overseas.
Employees, retailers, family members, even friends of family members were "assigned" to Leitz sales offices in France, Britain, Hong Kong and the United States.
Leitz's activities intensified after the Kristallnacht of November 1938, during which synagogues and Jewish shops were burned across Germany.
Before long, German "employees" were disembarking from the ocean liner Bremen at a New York pier and making their way to the Manhattan office of Leitz Inc., where executives quickly found them jobs in the photographic industry.
Each new arrival had around his or her neck the symbol of freedom - a new Leica.
The refugees were paid a stipend until they could find work. Out of this migration came designers, repair technicians, salespeople, marketers and writers for the photographic press.
