Kirk Douglas, born Issur Danielovitch, wrote in his autobiography that he had only been able to pledge one fraternity, a Jewish frat, while in college, and known as Issur Demsky. The fraternity was made up primarily of Jews of German heritage, and they were broad minded enough to invite the apparently Polish “Demsky” to join. But between the extension of the invitation, and pledge night, they discovered his family was actually Belorussian, and cut him cold.
Thank you for that interesting bit of info.
Here's an excerpt from the book "Hitler's Jewish Soldiers."
Hans Muhlbacher was a half-Jew, serving as an Unteroffizier in the Wehrmacht. He was stationed in Poland. His diary entry dated 14/5/1941 says:
"The Jews are dressed better on Sunday and go outside the ghetto (Ropczyce, Poland). I walk through the ghetto. It's awful what horrible people I see there. With grimacing faces they lean against the doors of their homes and businesses and stare amazed at the tall officers walking by.....Truly two worlds stand opposite one another...The Jews give the impression of being the eternal Ahasverus.* The Jews make a much more decadent impression probably due to centuries of inbreeding."
*[Ahasuerus is a name applied in the Hebrew Bible to three rulers and to a Babylonian official in the Book of Tobit.]
Muhlbacher was discharged from the service a short time later because he was half-Jew. He had been an engineer before the war, and went to work at Peenemunde on the guided rocket program designed to sink enemy ships.
