BEDLAM!
No, really:
"While Viennese artists, architects, psychiatrists and patients were working together, Londoners were developing one of the oldest surviving institutions caring for the mentally ill: the Bethlem Royal Hospital, or Bedlam. Join our guests to find out more about what was happening in psychiatry in London and Vienna at the turn of the 20th century."
