​The Princess Margaret announces the passing of Dr. Hans Messner


With heavy hearts we announce the passing of Dr. Hans Messner of Princess Margaret Cancer Centre. 

For over 40 years, Dr. Messner dedicated his life to Princess Margaret Cancer Centre. Dr. Messner began his career at The Princess Margaret in 1969, as a PhD student under the supervision of Dr. Ernest McCulloch; one of the “Fathers of Stem Cell Science." 

In 1975, Dr. Messner became an official member of staff at The Princess Margaret and in 1976, performed the first bone marrow transplant. 

His career continued to soar, and more recently he was honoured with the ASBMT Lifetime Achievement Award.

The award is granted to those who have made continuous clinical and scientific contributions to the field of blood and marrow transplantation. 

Earlier this month, The Princess Margaret’s Allogeneic Transplant Program was renamed in his honour. 

From all of us at the Foundation, we send our deepest sympathies to family, friends, patients and colleagues. He will be deeply missed.
