Freud's

Freud's insights into human behavior led to him being honored as a profound thinker.

Basing his invention of public relations on his uncle Sigmund Freud's psychoanalytic theory, Edward Bernays has left a lasting legacy on the media and how they interact with their audiences.

Even though most of Sigmund Freud's theories have been debunked, he was still way ahead of his time, and was responsible for sparking a new wave of psychology.

Carl Jung's theories were even wilder than Freud's.
