In Memoriam: Professor Ray McMahon 

30 October 1956-18 February 2025

It is with deep sadness that we remember Professor Ray McMahon, a beloved figure in the global pathology community and a pillar of the International Academy of Pathology (IAP). Ray passed away on February 18, 2025, following a brief illness, leaving behind a legacy of excellence, warmth, and unwavering dedication to the advancement of pathology.

Born in Galway, Ireland, Ray trained in medicine at University College Galway, qualifying in 1979. His journey in pathology began in his hometown and continued in Manchester, UK, where he built a distinguished career as a Consultant Histopathologist at Manchester Royal Infirmary and later as Professor of Gastrointestinal Pathology at the University of Manchester.

Ray’s contributions to education were profound. He was a passionate teacher and mentor, known for his patient and personable approach. He taught generations of medical, dental, and nursing students, and held key roles in curriculum development, admissions, and assessments at Manchester Medical School. His commitment to training extended to the Royal College of Pathologists, where he served as a trainer and examiner.

Within the IAP and its British Division (BDIAP), Ray’s leadership was transformative. He served as Treasurer of the BDIAP from 1996 to 2008, President from 2018 to 2020, and was the General Secretary of the IAP from 2014 until his passing. His financial stewardship and diplomatic leadership helped shape the future of both organizations. In recognition of his service, he was awarded the Cunningham Medal in 2016 and the President’s Medal in 2024.

To honor his legacy, the BDIAP has established the Ray McMahon Lecture as part of its educational program—a fitting tribute to a man whose life was devoted to learning, teaching, and service.

Ray is survived by his wife Claire, daughters Aoife, Niamh, and Sorcha, and his beloved grandchildren. Our thoughts are with his family, friends, and colleagues around the world. His impact on pathology and the lives he touched will be felt for generations to come.
