Answer
No, Melanie Klein did not originate from a psychoanalytical family. She was an individual contributor in the field. Her parents were not psychoanalysts and she did not receive any formal training in psychoanalysis. However, she was influenced by the work of Sigmund Freud and Karl Abraham, and she developed her own unique approach to psychoanalysis. Her work has been influential in the development of object relations theory and child psychoanalysis.
