Have a read of this:
The Leica Freedom Train.
The Leitz family, owners of the famous optical firm in Wetzlar were Protestants. The family supported one of the democratic political parties in Germany at the time the National Socialists gained control of the country and began their well documented punishment of their Jewish countrymen. With the increasing intrusion of the Nazi government into business and social life, Leitz quietly began assessing the effect of government policy on its staff and German dealers, many of who were Jewish. Leitz began a practice of buying back stock from affected dealers, reselling it to any who emigrated to America. From there they began 'hiring' people associated with the firm who were at grave risk. Each new employee was quickly trained to use and demonstrate the Leica. After training, Leitz applied for an exit permit to send the new 'employee' to America to assist in generating sales.
In America, the Leitz subsidiary worked hard to find jobs for these emigrants - some with little or no English skills. It was said that an editor of the Leica Magazine called every Leitz account in America to help place the new employees. It was also rumoured that Leitz paid full salary for three months and half salary for the next three months. In all, it is estimated some 300 or more people benefited from the program. To the German government, the program was transferring skilled salesmen to America to generate hard currency sales.
