Sir Brian Barratt-Boyes
Born in 1924, Sir Brian became one of the world's most eminent heart surgeons, famous for his development of techniques to replace defective heart valves and for finding new ways to treat babies born with heart defects. In the 1950s, he pioneered the development of cardiopulmonary bypass in New Zealand. Despite many opportunities to move overseas, Sir Brian remained with his team at Auckland's Greenlane Hospital. He died in 2006.
