As president of Orbis International, the flying eye hospital, Oliver Foot was responsible for saving millions of people worldwide from blindness, most of them in the developing world. To the charity he brought not only indomitable energy and charismatic and witty leadership, but fund-raising skills that, over the years, brought Orbis more than $200m in funding. He was a lifelong socialist and humanitarian, and a member of an impeccably left-wing aristocratic family; his uncle was the Labour leader Michael Foot. His other great passion was Jamaica, the country of his birth, an island he championed throughout his life and that, according to his wife Gail, "held his soul and heart".
