Hans Rosling knew never to flee from men wielding machetes. “The risk is higher if you run than if you face them,” he says. So, in 1989, when an angry mob confronted him at the field laboratory he had set up in what is now the Democratic Republic of the Congo, Rosling tried to appear calm. “I thought, ‘I need to use the resources I have, and I am good at talking’.”
Rosling, a physician and epidemiologist, pulled from his knapsack a handful of photographs of people from different parts of Africa who had been crippled by konzo, an incurable disease that was affecting many in this community, too. Through an interpreter, he explained that he believed he knew the cause, and he wanted to test local people’s blood to be sure. A few minutes into his demonstration, an old woman stepped forward and addressed the crowd in support of the research. After the more aggressive members of the mob stopped waving their machetes, she rolled up her sleeve. Most followed her lead. “You can do anything as long as you talk with people and listen to people and talk with the intelligentsia of the community,” says Rosling.
He is still trying to arm influential people with facts. He has become a trusted counsellor and speaker of plain truth to United Nations leaders, billionaire executives such as Facebook’s Mark Zuckerberg and politicians including Al Gore. Even Fidel Castro called on the slim, bespectacled Swede for advice. Rosling’s video lectures on global health and economics have elevated him to viral celebrity status, and he has been listed among the 100 most influential people in the world by the magazines Time and Foreign Policy. Melinda Gates of the Bill & Melinda Gates Foundation says, “To have Hans Rosling as a teacher is one of the biggest honours in the world.”
