An innovator and the father of histopathology education in Canada
Dr. Charles L. Pierre Masson pioneered revolutionary processes in histology and created one of the most brilliant schools of pathology of the 20th century. He was best known for his pioneering investigations of tumours of the brain and nervous system and for his histological techniques, such as the trichrome stain. Of particular importance was his work with the nervous system of the neuro-nevi, nerve lesions of the appendix and studies of specific types of brain tumours. He remained a modest man, completely devoted to histological research and the pursuit of improving, inventing and performing his laboratory techniques.
