James Joyce

Irish novelist who wrote Dubliners, A Portrait of the Artist as a Young Man, Ulysses, and Finnegans Wake — the most formally innovative fiction of the 20th century — and whose daughter Lucia's schizophrenia led to consultation with Jung (who diagnosed her as truly psychotic while Joyce himself, Jung said, was diving where his daughter was drowning).

Created the most technically demanding challenge to Jungian literary analysis — Ulysses's stream of consciousness and Finnegans Wake's dream language are the literary equivalents of free association and primary process thinking — and Jung's diagnostic distinction between Joyce and Lucia (the schizophrenic diver vs. the genius) is one of his most famous clinical observations.
