In 1975, this pursuit led to the development of the McGill Pain Questionnaire, now used in pain clinics and cancer hospices around the world. Melzack spent time at the University College of London, and the University of Pisa in Italy. He eventually became a faculty member at the Massachusetts Institute of Technology (MIT) where he met Dr. Patrick Wall. The two shared similar thoughts and ideas surrounding the phenomenon of pain. Melzack and Wall noticed that some individuals felt immense pain when damage to the body was minimal, and some people with traumatic injuries experienced little or no pain until a later time.
