Why was St. Mary Bethlehem also known as bedlam in 1957?

St. Mary Bethlehem, a psychiatric hospital founded in the 13th century in London, became widely known as "Bedlam," a term that has since come to symbolize chaos and madness. By 1957, Bedlam was emblematic of the often inhumane conditions and treatment of the mentally ill, reflecting the stigma associated with mental health care during that period. The name "Bedlam" itself derived from the hospital's original name, and it was frequently used in literature and popular culture to represent the perceived disorder within mental health institutions.
