Sigmund Freud was an Austrian neurologist who founded psychoanalysis, a method for treating mental disorders and a theory of human behavior. His central claim was that unconscious thoughts, wishes, and conflicts shape much of what people do, often more than conscious reasoning.
According to multiple authoritative sources, Freud argued that psychology must investigate hidden mental processes. He developed a therapeutic approach—psychoanalysis—designed to bring those unconscious elements into awareness. His major innovations included the concept of repression, the importance of infantile sexuality, and the tripartite model of the mind: id, ego, and superego.

Who Was Sigmund Freud? Key Personal Life Details
Freud was born in 1856 in Freiberg, Moravia, into a modest Jewish family. He was the oldest of eight children. His mother, Amalia Nathansohn Freud, was his father’s third wife and reportedly a powerful influence on him. Freud once said, “A man who has been the indisputable favorite of his mother keeps for life the feeling of a conqueror.”
He studied medicine at the University of Vienna and began his career as a neurologist. In 1885, he studied under Jean-Martin Charcot in Paris, which sparked his interest in hysteria and unconscious processes. He married Martha Bernays in 1886 and had six children: Mathilde, Jean-Martin, Oliver, Ernst, Sophie, and Anna. Anna Freud later became a prominent psychoanalyst herself.
Freud had six children with Martha. Their son Ernst became an architect, while Anna, the youngest, followed her father’s path and made significant contributions to child psychoanalysis. The Britannica entry provides additional details about each child.
