Hans Rosling

Hans Rosling (1948–2017) was a Swedish physician and professor of international health at the Karolinska Institute. He worked as a district medical officer in Mozambique and spent two decades researching konzo, a paralytic disease tied to poverty and diet. In 2005 he co-founded the Gapminder Foundation with his son Ola and daughter-in-law Anna Rosling Rönnlund, and his widely watched TED talks used animated bubble charts to explain global development data.
