Developed the treatment for (Rhesus) Rh disease

Dr. Bruce Chown

An expert clinician, diagnostician, innovator and teacher

Dr. Bruce Chown became a pathologist at the Children's Hospital in Winnipeg and devoted his career to studying erythroblastosis fetalis, a fetal blood disorder often known as “Rh disease”. The disease occurs when a pregnant mother has a different Rh factor than her unborn child, causing her immune system to attack the baby, leading to devastating complications in the development of important organs such as the heart, lungs and brain, or even death in utero or post-delivery.

Dr. Chown subsequently set up a facility along with Connaught Laboratories to manufacture Rh immune serum. His work resulted in the prevention of the vast majority of potential Rh disease in Canada and elsewhere in the world.

Key Facts

Became the first pediatrician in Manitoba

Involved in prevention of kernicterus, a brain disorder, by replacement transfusion and prevention of stillbirth by early delivery

Before Dr. Chown, Rh disease accounted for 10% of all fetal and neonatal deaths in Canada

Professional timeline

Impact on lives today

With a keen intellect and scientific curiosity, Dr. Chown was an innovator whose work had a profound impact on the field of medicine. Once a widespread and deadly, Rh disease is now rarely seen in many countries of the world. Where the disease does exist, Chown’s work continues to save lives. His Rh immune globulin is still sold in 35 countries by Manitoba-based research firm Cangene.
