Axel Hellstrom (December 22, 1893 – July 22, 1933) was a German muscle reader, mentalist and stage magician. He redefined the art of muscle reading to such an extent that this technique, also known as "contact mind reading" and "Cumberlandism" (after a 19th-century practitioner named Stuart Cumberland), is now best known by the name "Hellstromism".[1]
