Alfred Wolfsohn
Alfred Wolfsohn (23 September 1896 – 5 February 1962) was a German singing teacher who suffered persistent auditory hallucination of screaming soldiers, whom he had witnessed dying of wounds while serving as a stretcher bearer in the trenches of World War I.
After being subsequently diagnosed with Shell Shock, Wolfsohn failed to recover in response to hospitalization or psychiatric treatment, but cured himself by vocalizing extreme sounds, bringing about what he described as a combination of catharsis and exorcism.
Inspired by the range and expressiveness of his voice, which resulted from the vocal exercises and techniques he developed in an attempt to heal the symptoms of trauma sustained during the war, Wolfsohn began teaching others, acting as both a singing teacher and psychotherapist, seeking to combine the principles of both disciplines. Wolfsohn had no formal training in either field, but nonetheless became a critic of traditional vocal pedagogy and an advocate for the principles of Analytical Psychology developed by Carl Jung.
