The man whose blood saved millions has passed, but his legacy lives on.
James Harrison, known around the world as “the man with the golden arm,” died in February 2025 at age 88 — leaving behind one of the most extraordinary humanitarian legacies in medical history.
According to CBS News, Harrison’s blood plasma contained a rare antibody called anti-D, used to prevent Rhesus disease, a condition that can be fatal for newborn babies.
Because of this rare antibody, treatments developed from his plasma are credited with saving the lives of around 2.4 million babies.
His journey began after a major chest surgery in his youth, when he survived only because of donated blood. Grateful — and determined — he promised to give back. Doctors later realized his plasma was uniquely valuable, and Harrison went on to donate more than 1,100 times over six decades.
The Australian Red Cross called him one of the most important blood donors in history. He became such a vital national figure that his donations were carefully protected, continuing until he retired at age 81.
One man.
One rare antibody.
Millions of lives saved.
Sometimes, heroism flows quietly — one donation at a time. 🩸💙
