Conversation so far:
What was the psychoanalytic turn?
at the age of thirty I wrote a letter out of the blue to Freud, asking him if he would take me on as a student.
Did Freud take him on?
So there I was, launched on the treatment of patients, with no experience, with no supervision, with nothing to help me but some two years of analysis with Freud.
Are there any other interesting aspects about this article?
James subsequently began publishing his own original articles; and the two of them (in collaboration with Jones and Joan Riviere) began translating Freud's works in earnest.
What other work did he do?
Their translation of Freud's works, in twenty-four volumes, remains the standard edition of Freud's works to this day.

Question: What else was his known for?
Self-contained rewrite: What else was James Strachey known for other than the psychoanalytic turn, and publishing articles in collaboration with Jones and Joan Riviere translating Freud's work?
