Rosa Bernhardine "Bernile" Nienau (20 April 1926 – 5 October 1943) was a German girl who became known as "the Führer's child" because of her close friendship with Adolf Hitler that lasted for six years from 1933 to 1938.

Hitler knew and loved her despite her being a FULL QUARTER jewish. That's too much for even me but the Fuhrer was ok with it.
