Pappius was a pioneering researcher at The Neuro for close to seventy years

The Neuro extends its condolences to the family, friends and colleagues of one of The Neuro’s most distinguished scientists Professor Emerita Hanna Pappius, OC, PhD, who passed away on March 29, 2023, at the age of 97.

Hanna Pappius was born in Poland and completed her scientific education at McGill University with a BSc in 1946, a MSc in 1948 and a PhD in 1952. She joined the Donner Laboratory of Experimental Neurochemistry in 1953, working with KAC Elliot. She was a Professor in the Department of Neurology and Neurosurgery, and an Associate member in the Department of Biochemistry, McGill University.

A dedicated, pioneering researcher and colleague at The Neuro for close to seventy years, Professor Pappius made significant contributions to her field by pursuing studies on cerebral edema and the effects of brain injury on neurotransmitter and receptor mechanisms. She published more than 100 scientific papers over her distinguished career. She also co-authored a book entitled Brain Electrolytes and Fluid Metabolism, now considered a classic in the field.

She mentored and trained many experts who are now internationally renowned neurologists and neuroscientists. Following her retirement from lab science in 1995, Pappius served as Chair of The Neuro’s Animal Care Committee until 2016 and Co-chair of the Research Ethics Board for more than a decade, both critically important for the research enterprise.

Among her numerous honours are the Order of Canada, the Commemorative Medal for the 125th Anniversary of the Confederation of Canada in recognition of significant contribution to compatriots, community and to Canada (1992), the 1993 Award from the Polish Minister of Foreign Affairs for her outstanding contribution to the advancement of Polish culture in the world, and a Neuro Lifetime Achievement Award (2005) in recognition to her lifelong commitment. In 2009 the honorific Emerita Professor was conferred upon her by McGill University in recognition of her years of devoted and meritorious service as Full Professor.
