Freud's nephew is the "father" of public relations.

I would venture to say he's the step father, the real father being Ivy Ledbetter Lee...
but he's not credited with the father title, because of a choice to work with a German company during WWII, he is accused of being a nazi, and he died before he could defend himself against such acusations.

So Freud's nephew, Edward L. Bernays gets the wonderful father title.

How cute.
