Sigmund Freud

Sigmund Freud was born on 6 May 1856 in the Austrian Empire (now Czech Republic) and became one of the most influential thinkers of the early twentieth century. He is considered to be the founder of psychoanalysis and is famously known for his theories about the unconscious mind, the importance of dreams and the sources of psychopathology. He is most renowned for his books The Interpretation of Dreams (1899) and The Ego and the Id (1923). After a long and painful struggle with cancer of the jaw, he passed away in London on 23 September 1939.
