Jones, Ernest, 1879–1958, British psychoanalyst, b. Wales. He taught (1910–13) at the Univ. of Toronto and was director (1908–13) of the Ontario Clinic for Nervous Diseases. He founded the International Journal of Psychoanalysis and served as its editor from 1920 to 1939. In 1925, he founded the London Clinic for Psycho-analysis. A follower and colleague of Sigmund Freud, Jones was instrumental in introducing the study of psychoanalysis into England and the United States and coined the term rationalization as a corollary to the theory of defense mechanisms. Considered an authoritative biographer of Freud, his writings include The Life and Work of Sigmund Freud (3 vol., 1953–57) and Free Associations: Memories of a Psychoanalyst (1959).
