Hart Pomerantz in The New Yorker:
Originally, Freud analyzed only himself, and did so for five years, but he grew exhausted running back and forth between his chair and the couch. He then came up with the idea of analyzing patients, and continued to do so for the rest of his life. At first, Freud sat on the couch and the patient sat at his desk, but he changed places after discovering that his pens were disappearing.
It was around this point that Freud met Carl Jung. Freud was besotted with Jung—he was a male shiksa, as Adler once remarked. Freud denied such feelings vociferously and insisted that the fact that Jung was blond and had nice legs meant nothing, as these qualities were also possessed by Freud’s piano stool. Nevertheless, it was later revealed in Freud’s diary that, during Jung’s analysis, Freud would routinely stretch out next to him on the couch.
