Born in Chicago, Illinois, which is in the north central region of the United States.

That's strange.  I'm pretty sure he's German by birth
user
I didn't say that I was 100% sure.  I can also check in with his company and check, and get back to you when I know.
assistant
I think his dad was American soldier and married a German girl.
user
That sounds plausible.  I'll also ask for some sources to verify that when I check, if I can.
assistant
How many sons does he have?
user
I don't know.
