1997 INDUCTEE Pierre Masson, MD Cells, Genetics & Genomics, Health and Medical Education & Training

Born:

November 12, 1880

(Dijon, France)

Died:

May 11, 1959

Education:

MD, University of Paris; Pasteur Institute (1909)

Awards & Honours:

Became one of Canada’s most distinguished histopathologists of his generation

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.

Key Facts

Gained international recognition for his ground breaking investigations of the brain and nervous system

Was the first to describe the concept of neurocrine secretion, which led to modern neuroendocrinology

The “Masson trichrome stain” became the standard in all pathology laboratories

Published over 120 important scientific articles, in addition to his seminal textbook

Impact on lives today

Dr. Masson died in 1959, but his influence persists in the respected legacy of scientific originality he leaves behind, and in his innovative interpretations of lesions and tumours based on remarkably precise histological sections. For example, his work on fixation, colouration and argentation are important methods still in use today. Throughout his career, Dr. Masson gave pathology a new vitality that undoubtedly permeates through the generations of scientists touched by his mentorship.
