Just as Sigmund Freud upended and challenged the way society viewed the psyche and sexuality in fin-de-siècle Vienna -- Schiele reached the same results with emotionally charged works that reflected his inner turmoil, desires, and fantasies.

An amazing recent discovery of a handwritten diary from 1913 proves that such historic personalities as Freud, Adler, Wittgenstein, Hitler, Stalin, Schoenberg, Berg, Kokoschka, Klimt and Schiele knew each other intimately.
