The Freud Museum at Berggasse 19 in Vienna showcases among other artifacts from the psychoanalyst's life, his suitcase, stamped with his initials and the name of his adopted city. They also published a book called Freud's Travels. I asked what led him to choose travel as one of the defining metaphors of his work ... and hope listening like this evaporates borders. Special thanks to the musician, Dana Boulé.
