Freud was born May 6th 1856. One of his theories was about how your childhood sex life set your future adult i don't know how those are related at all or even acceptable to think about but i guess he did. Another theory is that people still think and work while unconscious even better then being conscious. Most of his problems is from being divorced so many times. He died September 23rd 1939 he asked his doctor to give him an overdose of morphine because he was dying from mouth and throat cancer.
